I bought the game during steam's summer camp sale and played a few games without any problems.
However, now whenever I start up the game, after the intro plays (in which the sound works fine) the window goes white and locks up for about 10 seconds and finally loads the main menu to show the sound is disabled.
Win7 x64, HTO Striker 7.1 sound card, Radeon HD 4850 x2.
The only settings I may have changed are some settings on my graphics card, and I have since reverted them. I have tried verifying the files via steam, deleting and re-downloading the game. Tossed in some reboots and played with the graphics settings in-game, removed my saves. No luck.
Any idea what went wrong?
