Hi. I have a problem running F.E.A.R demo: first I tried installing it on my gaming XP which is XP Pro SP1, but didn't work, so I installed it in my main XP (SP2) and the game install along with its so-called new directx was successful. But when I try to run it, before even the screen goes black, I get the following message: Application Error: ---------------- The exception Single Step A single step or trace operation has just been completed. (0x80000004) occured in the application at location 0x00000000. Click on OK to terminate the program Click on CANCEL to debug the program ---------------- Any ideas what might be wrong? I've tried without any OC too. I didn't bother trying different drivers, coz it can't be a driver issue when directx is not even initialized, right? i'm using official 66.93 drivers. any help is greatly appreciated. thanx in advance.
