I may have found the solution. I just completed a 3 hour tour from Lihue to Hilo without any problems after previously having CTD's within 20 minutes or so for the past three weeks.
The solution? The last post in this thread; http://flyawaysimulation.com/postx19265-0-15.html
I have a second installation of FS9 updated to 9.1 with no addons on a different HD, separate OS on same computer. No CTD's.
There are 32 dll files contained in the FS9/modules folder. These files can found on disc 2 MSGAMES3.CAB file time stamped 6/12/2003 8:36 PM. They can also be found in the FS9/BACKUP folder (backed up by the FS9.1 updater) The updated FS9.1 dll files (count 32) in the FS9/modules folder are time stamped 9/1/2004 2:46 AM. The funny thing is the 32 dll files in the sim I always fly were time stamped at 3
:46 AM. So I just copied the 9/1/2004 2
:46 AM files to the modules folder.
Whew! I hope this is it.
What could have changed the time stamp from 2:46 AM to 3:46 AM? Could this have been causing the CTD's?
