Has anyone ever had something like this happen? I have a 13" unibody MBP, and I installed XP on bootcamp. I installed civilization IV on XP and played it for a while. Booted back into OSX and used that for a while. Then I went back to XP and now everytime I try to start civilization IV I get a BSOD memory error on XP and it crashes. I'm going to go ahead and install Vista instead and hopefully I'll still be able to run Civ4 fine and not have it crash hard everytime I try to run it after booting between OSX and Vista. Anyone ever have something like this happen before? I find it strange that it didn't start crashing until I booted into OSX then back to XP.
