Unfortunately I haven't found any time doing some serious testing by flying with v 3.719. However I started FS and just left it by itself for a couple of hours and that went OK and FS was still running when I got back to the PC, before it most of the times terminated by itself within maybe 15 mins of so and sometimes even faster.

I have CH Manager v 3.60 installed...forgot to mention that in my previous post.

That's right, I'm using Win XP SP2 fully patched. Well...hope you'll find the problem eventually whatever it might be!

I'm sorry to hear that Pete, this is really a strange and annoying problem! My guess since we're a bunch of guys having this very same problem but still not all of us is that it's a combination of FSUIPC v 3.71 and - another program - a specific hardware combination These are the programs I'm using (part from FS9 of course ;-) ) GE Pro II Ultimate Terrain Europe FS Genesis World wide Mesh MyWorld2004 Landclass ASv6 Ultimate Traffic ActiveCamera FSRealTime FSNavigator Autower FSPassengers And my HW setup below ASUS P5W DH Deluxe motherboard Intel Core2 Duo E6600 2 GB Corsair Extreme RAM 2 x SATA Raid0 Arrays a 300 GB ASUS EAX 1900XTX 512 MB SB Audigy 2 ZS Realtek High Definition Audio Hope this can be of some help!

Pete, Did a test tonight and though I would share the result with you to try helping you narrowing down what's causing these CTDs. Come to think of today I haven't checked for new versions of my display drivers for some time. Checked ATI's website and noticed there was a new version of the official Catalyst drivers so I downloaded and installed them...went from installation package 6-8_xp-2k_dd_ccc_wdm_enu_35179 -> 7-1_xp_dd_ccc_wdm_enu_40211. After the upgrade of the display drivers I though I would give FSUIPC v 3.71 another try but...after loading FS it vanished by itself after approx 1 minute and I was back at my desktop... I then went back to v 3.70 and FS is running just fine so I guess you can rule out the display drivers beeing the culprit. Best, Richard

I am still trying to make 3.717 crash -- I managed to get one CTD with 3.715 using LeeWang's suggestions, but I can't so far make any CTDs occur at all, on one ATI-equipped PC nor two nVidia ones. It's a puzzle. It must be sorted -- I cannot support 3.70. Pete Let me know if you think I can be of any more help Pete. //Richard

Hi Pete, Sorry for not posting here until now. I was the one starting the thread over at AVSIM and since I got this tip from Lee going back to v 3.70 of FSUIPC I haven't had a single CTD. As for the GFX card I'm using an ATI X1900 XTX. All the best, Richard (WebMaximus)
