Muerta,
I totally feel your pain. But I am convinced the problem lies with your game account somehow. I have spoken with some computer insiders on this matter and they say that seemingly, my fix defies logic.
For anyone reading this for the first time, I literally swapped out every single piece of hardware on my system (processor, mobo, vid card, sound card, network adapter, ram, tried 2 different hard drives). I ran all 3 versions of the game, reinstalled windows, fdisked windows, etc. The problem is not likely hardware. The only reason I recommend the SiS chipset is because I witnessed the game running well on a system with it. So I migrated over to the board (it was only $66). I've also heard this several times 'it worked on my old system'. Perhaps there is a conflict with newer technology. To me, however, the key fix was exchanging my copy of the game. I read somewhere (and I've mentioned this previously) that the issue is a cookie. Having tested all my hardware, I have to agree that it is software. I exchange the copy of the game, started a new account, and have had no issues moving forward.
Before you throw in the towel, if possible, try getting a new copy and if you are up to it, reinstall a clean version of windows one more time. After playing the game this week, I have to admit, it is pretty bad-ass. As much disdain as I have for EA right now (and am learning they are not alone in poor support of their product) they made a hell of a game when it runs.
Knowing what I went through to get it to work, I hope everyone who has problems can find a fix and enjoy the game. It's simply the best FPS out right now (minus these ridiculous problems, of course).
