Didn't want to post this under the games section since it's not as popular, and a game is an application anyway, right? Anyways, my game is saved at the very end of Delta Labs 3. When I complete that level and start to load Delta Labs 4, the loading bar gets about 1/4 of the way then Doom 3 crashes back to the main menu with no sound. I had this problem a couple levels before, but once it crashed back to the main menu, I could then try and load the level again and it would load, but it would play very choppy. Now everytime I try to load Delta Labs 4, it just crashes back to the desktop. I can't figure out what is causing the problem. I'm using the 61.77 drivers and the latest SB Audigy drivers. I also tried disabling my soundcard, which didn't help, so it's not a sound issue. I've got the latest chipset drivers installed, along with the latest BIOS. I disable Norton Antivirus and ZoneAlarm and close EVERYTHING else out, but it still will not load. I also tried using the cheatcode to just load straight to Delta Labs 4, but it will not do the trick. Graphic settings are at 1024x768, all effects set on, medium texture quality. Any ideas are welcome, I really want to finish this game.
