I had a succesful patch but when I try to start FS9.1 it crashes to desktop. I have Updated both FSUIPC and Active Camera but it still won't start. Are there any other modules that need updating? I've read all the threads and can't find anything...Steve G

Steve,you say you updated Active Camera, I guess to version 2.0.But did you install the Active Camera patch for FS9.1 (if you didn't it will cause a CTD). You can download the patch at http://www.anticyclone.be/AC2004patchFS9_1.zip

Yes, I did get the patch, but I think I installed it and Fsuipc before I did the 9.1 upgrade. Reinstalled again after 9.1 upgrade and things seem to be working. I think that HostSB may still be causing some instability though. It may take some time to figure out some with all the modules out there..Steve G.
