At London Transport Flying Club we have two computers, one running XP the other Windows 7, fed through a BT hub.
We have had an on-going fault for several days with SkyDemon Light, in that the chart stops downloading with a few byes to go. After a minute or so, an error message is displayed. I've tried on both machines and on IE, Firefox and Chrome on both machines, and I've re-started the machines and the Hub.
I can only conclude that the problem is not with us. It was all fine till a few days ago.
Any thoughts?
Here are the screen shots -

Further -
I've been checking around, and similar problems are reported elsewhere in a Silverlight context. Could it be that some applications built with it expose a bug in the system? I couldn't find any workable answers. I tried emptying the cache, reloading Silverlight, different browsers, restarting computers and the router......nothing worked. And yet it runs fine at home.

I have experienced the same problem for the past few weeks. I have not used the SDLight site for a few months until early January. I thought it may be a transient problem so did not report.
My Silverlight version (4.0.60531.0) has not changed since I last successfully used the site, but my browser versions probably have (IE, FF and Chrome). PC is Vista SP1
Just in case it's relevant I too have a BT Hub and this changed late last year. (I did read on a BT forum that their Fibre hubs were causing some other weird problems with certain web based software. Could be a red herring.)

Additional: I just tried with IE 8 (not my usual browser) and got a different error. See attachment

OK, I was bored, so I checked to see if the herring was red 
I switched back to my old (slow!) broadband link with Netgear hub, using the same PC. The chart downloaded successfully!!
I switched back to the new bb link with BT hub and the chart still displays. But I think this is because it is cached - it appears instantly. Clearing all the caches from Chrome and IE does not cause it to reload. I was hoping(?) to prove that it would fail again when accessing through BT hub. Can the chart be forced to disappear somehow?
So if this is a BT hub-related problem, is there anything the SD developers can do to workaround this? I *really* don't want to try explaining this issue to BT's call centre staff!!

I've seen that error too, on one of the many options I've tried. Could well have been IE8.
Anyone from Sky Demon want to comment?

Yes it can be forced to refresh: right-click on the welcome/disclaimer screen, go to application storage and delete all files for the skydemonlight.com domain. It will then be forced to re-download.
We (SkyDemon) can clearly see that something is affecting a few users trying to download the UK chart. Nothing about the SkyDemon Light service itself has changed, though, and most users seem to still be ok. So basically we're still scratching our heads about it. The error posted above does indicate that something is changing the file, though, so that SkyDemon quite rightly rejects is as not being what it was expecting. I wonder if there's something in common such as a particular type of router/hub or other networking hardware here?

Thanks Tim, I deleted the chart, and I again got the problem when using my BT link. How often does the chart get refreshed and thus need downloading? If I download it today, will it be out-of-date tomorrow?
Bernard - can you share information about your broadband? Mine is BT Infinity for Business, with a 2-Wire BT 2701HGV-C hub.
You say you began getting this error a few days ago. What changed? A new bband link? A new hub? It is possible that BT upgraded your firmware to a later version on the quiet as seems to be their annoying habit.
They did this to me and it is conceivable that this is what broke the site access for me - I can't remember whether I ever accessed SDL prior to the upgrade. The version I am at now is the one that has caused other problems (BT did halt the firmware upgrade roll-out for a while, but resumed again (with changes I think) in December).
If you have a 2700-HGV or 2701-HGV hub (or similar) interact with it by browsing to "http://home". If it's like mine you will see the hub model top-right. Click that icon and you should get info about the hub. What is the exact firmware version?
Finally, see if you can find when the hub rebooted. There is a "time since last booted" item. Does this coincide with when the problem started? There is also a "logs" tab. You may be able to search and filter this to see if/when a firmware update was done. And at that Logs page, click "Upgrade Info" to see if the firmware has been changed at some point.

Model: BT2700HGV
Hardware Version: 2701-100589-005
Firmware Version: 6.3.9.63-plus.tm
Manufacturer: 2Wire, Inc.
Upgrade Log
Current Version 6.3.9.63-plus.tm
Initial Software Version 6.1.1.48.1-enh.tm
bt-unified.download_plus: 6.3.9.63
There's no upgrade date logged.
The logs didn't have anything very comprehensible, so I cleared them and ran the download again. No events logged. Thev last re-boot was us a couple of days ago trying to clear the fault.

Just wanted to chip in that I cannot load the UK chart on EITHER SD Web OR SD Plan. In fact I can't at the moment think of anyway to plan a UK flight..anyway, I guess that rules it out as a browser or silverlight problem for me.
