Hey. This is what happened and is happening. I had the game since I was on windows vista and it was working perfectly well, now I'm on XP and strange things began happening. When I start the game, it seems pretty normal, all the sounds are in place while the intro's on, but then game starts to load and there is completely NO SOUND from this point, in My F1 audio options I can't choose audio drivers, don't know if this has something to do with it. And more importantly - game crashes when you try to run any of the race - whether it's time trial, grand prix or season mode, game's loading for 10 seconds or so and crashes right on the loading screen - I get application errors every time I run a race. Any ideas on this? Thanks in advance. P.S. I'm not using my integrated audio card as I've got another one, but it doesn't seem to be a trouble in any other games. P.P.S. I tried reinstalling the game, reinstalling GFWL, nothing helped. By the way, here's my quick system information: NVIDIA GeForce 9800 GT (512 MB) Q9400 @ 2.66GHZ CPU 3.50 GB of RAM External sound analog Fireface 400 Old internal sound card Realtek HD Audio Hard Drives: SAMSUNG HD502IJ (465 GB, IDE); ST31500341AS (1397 GB, IDE) Hope you guys come up with something here, as codemasters forum didn't have any suggestions. Thanks.
