Computer locks up in CoH

I just started playing CoH again yesterday, downloaded the client, started playing, and changed the Ultra settings slider from recommended to quality, hit accept, and my computer locked up. Every time after that when I load into a character my computer freezes and I have to restart. I added the line -useTexEnvCombine to the end of the shortcut target to get into the game and I could play fine (with horrible graphics because of that command). I changed graphics settings back to recommended, applied, exited CoH, removed the command from the shortcut, loaded CoH, and my computer locked up when I loaded a character. My CoH runs perfectly fine (besides terrible graphics) using the shortcut command, but my computer locks up when I don't use it. Is there a specific setting that is causing this lock up?

I'm running Win 7 64-bit, Intel Core 2 Quad @2.4Ghz, 4Gb RAM, ATI Radeon HD3650, Dual Monitor (extended, but only run CoH in my main monitor)

Any help on this would be greatly appreciated.

Thanks in advance.
