Umberto, I hope you don't mind me asking this question here rather than at the Cloud9 forum, I figured the answer would be from you and most likely faster on your own forums!
I've recently re-installed Bergen, I use the latest scenery files and the latest version of the add-on manager (I believe). However, when booting up FSX I get the error message that you can see in the attached image. The thing is though, if I go to Bergen I can see the scenery fine and FSX doesn't "quit". Is there anything I might have missed to fix this?
Thanks in advance.
