Aye, I changed my password, and I think the emails might be correct. I haven't opened my email in a few months, looking at my purchase history in my account, the amounts seem to be matching up, it's just that all the emails were dated as being sent today, so I freaked cause it looked like an account hack, dunno why my ISP…
I'm running a Crossfire rig and it's been working fine for me with no hassles at all: Are you sure your not running in windowed mode? Both Crossfire and SLI need to run in full screen mode to work, any form of being windowed and it will cancel out one of the GPU's.
