Can someone help me please?
Help is *usually* available 24/7 on Saturdays and Sundays, but you cannot expect or demand it would always be...
Now the problem: since it doesn't happen here, and we cannot replicate it, and so far all users that reported it seems to use P3D, we are suspecting there's some kind of bug in P3D that we are being sent exception error caused by other addons.
There's nothing "wrong" with the Beta but, BECAUSE it's a Beta, we are trying to be more picky about errors, we are simply logging error that you might always had before, but that we didn't care to report. And because it's a Beta, we require the program to alert you and stop, so you can notice the error and report it.
If it's ok for you, we can have a Teamviewer session, so I could look at your system directly, and send you special debug tools we have. PM me to arrange it.
