Doom 3 BFG Edition hangs on loading screen
Had the game for a while, but recently an issue has cropped up that's preventing me from playing it. Whenever I try to continue the game or start a new one, the game hangs on the first loading screen and refuses to load the level. There is no error screen, no crash, and the game refuses to do anything but track my mouse pointer unless I press the ESC key, at which point it just closes the game.
I'm running Vista 64 (latest service pack), with a Radeon 6950, Phenom II 945, 8 gigs of DDR2 800 RAM, a 780g chipset, a Seasonic S12II 520 watt and a Western Digital Caviar Black 1T hard drive. I have the latest drivers for my VGA.
I've tried reinstalling DirectX, forcing window mode, closing Afterburner, and changing the game's settings. I even deleted my save files because I thought they might be corrupted, and reinstalled the game twice. It's aggravating, to say the least. I would try tweaking OpenGL settings, but Catalyst Control Center only allows me to alter the Triple Buffering setting (which is off). Everything else is set at default and is linked to my Direct X settings.
