I've got the same problem which I thought was caused by the Honeycomb Bravo which had just arrived. I spent days trying to diagnose the problem uninstalling, reinstalling, posting on forums.
If Aerosoft had just acknowledged that there is a problem with the latest update and got to work on it, the word would have got around and saved an enormous amount of peoples time and frustration.
The CRJ is removed from my system and they may well be permanent and for a very expensive aeroplane that really isn't good enough when you have the likes of the FlyByWire and WorkingTitles giving their excellent and fault free models away for free.
I thought Aerosoft were one of the best, but not if the product doesn't work.
