just the description of the problem:
I already had the new addon manager (by Cloud9) --- and the FS9 worked fine
(I already use sceneries like BErgen, KLAX, EHAM --- also work fine i.e. latest versions)
I installed Zurich and CTD at starting up FS9 / no error message
I unistall Zurich and still CTD / no error message
I manually delete all three bglman files and reinstall the latest addon manager again ---- FS9 works fine again!
now it is your turn
