Something really strange is happening.Sometimes FS9 will just suddenly close without any error messages.If I try to reload the flight from an Autosave file it will shortlyafterwards close down again. Funny thing is that sometimes I can flyfor hours without any problem. Would appreciate any advice/suggestion/indication about possible cause.Thanks in advance.

Shot in the dark, but if you're using Win2K or above, check the Event Viewer and see if there's anything there. Also see if it keeps crashing in the same area that you fly in.

Yes you are right there are some error events there just at thetimes of the crashes, but I cannot understand what they refer to.Any ideas how to decipher these?Thanks

Joaquin,E-mail me the screenshot of the event viewer as well as the details of it and I'll try to help you.

StevenApologies for not getting back to you sooner.Messages on event log I found were to do with something else(O&O defrag)and nothing to do with FS9. Having said that I have noted some details of when and how this problem occurs.Last night while taking part in a VATSIM event, all went welluntil I began to descend and traffic around me increased.Suddenly screen goes black, monitor looses connection and PC although still showing the green light is unresponsive and for all intents and purposes it seems that whatever causesthis problem kills not only FS9 but Windows XP. This only happenswhile running FS9.Not sure what else to do. Would reinstall FS9 if I knew thiswould cure the problem.Thanks

Look for duplicate AFcads and if you don't find any, try rebuilding your FS9.CGF file. Make a backup first and write donw your settings in the options page so you can reset them in the new config.
