Before anyone reads any further on this post, I am going to be mentioning 1 very known addon program and the partner to that program. The program is fsuipc (3.135 version) and pfc.dll (1.83). Before anyone jumps to any conclusions, I am NOT blaming what has happened on these programs, I am only going to explain what has happened since the install of these programs on the system.I was having several CTDs when simply exiting the sim. I could fire up the sim, goto the default KDEA with the 172, allow the plane to sit on the runway for 10 seconds, hit the close button, and I would get a gauranteed CTD involving nt.dll atc.dll weather.dll etc.. I thought at first it might be my sound card as I am running a Hercules Fortissimo III 7.1 with non WHQL XP drivers.. not being able to cleaning strip the drivers out, and up for some experimenting today, I reformatted my HDs and did a fresh XP install with no soundcard installed. I proceeded to add all the ASUS P4S533 drivers, the XP service packs, DX9b, and the Radeon 4.1 drivers, then installed COF. I set my display settings up, loaded up the normal default setting at KDEA described earlier, let it sit 10 seconds, closed out, and got a clean exit. I tried this several times proving to myself it worked. I then added in the fsuipc and pfc dll files, got a message from pfc.dll that I needed to select my com port. I went to the defualt setting, closed out, and bang CTD. I loaded up the sim again went to the default setting, selected my com port, exited the sim, and bang another CTD. Reloaded went to the defualt, closed out , exits clean. Reload, back to defualt, call up the menu to alter my aircraft settings, close out , CTD. Come back into the sim, go back and realter my ac setting as the CTD has not allowed them to save, exit out, its OK... go back in, call up PFC.dll to alter some of my buttons, exit out CTD. Now the trend I am seeing is this: If I access a menu, or the dll dialog box to alter anything, it seems to be wanting to write something (some kind of new config setting) but for some reason when I exit out after accessing, I get a CTD..Has anyone else experienced this at all... I will be posting this on Petes forum as well... like I said, I am not pointing fingers at the files, only explaining what has happened since the addition of them, I have no other addon programs installed in the sim, just XP SP1 and a bare bones COF.Thanks,Chris

On a sidenote I have all my configs set now for the sim and PFC equipment, soundcard reinstalled, and have tried about 10X now to start up, and close at KSEA and no CTD yet...W E I R D

On a total sidenote-I haven't had any Ctd's with cof.I however fired up Print shop Deluxe today to make an ad and was surprised when-everything was invisible! I blinked-I tried it on my other computer-everything worked fine-except on mine I couldn't see anything. I downloaded a patch-still nothing. FS2004 and everything else runs fine on my 'puter-everything runs fine, I could see my document in preview mode-I could print it-but it was invisible in the normal viewpoint.After trying much-I unistalled my current nvidia driver-then reinstalled it.Bingo-Print shop working-fs2004 still working-no improvements...Computers are funny things....http://mywebpages.comcast.net/geofa/pages/rxp-pilot.jpg
