Yeah, the X-Fi Platinum. I saw something about it too, but when I didn't have any issues with any other games, music, etc., I wasn't sure if that was it. Looking back it seems to have been an issue with the X-Fi card, xp64, and BF2, because everything else ran fine.
Doesn't matter now - I'm already back up and running on XP Pro (NOT x64), with everything installed and A-OK.
