How strange. Is there any more to the error details, at the top rather than the bottom of the text, that you could share? The route opening functionality is not linked to the direction indicator, or in fact any of the instruments, in any way.If you could share the route you're attempting to open, we'll try here to reproduce the error.
The trial version of SkyDemon runs for 30 days only, and for 30 minutes at a time (for the navigation part). Unfortunately if you've reached the end of the trial there's nothing we can do to reset it for you, but when the next version is released (around a month) that will begin a new trial period.
