引用自 DietDrPepsi：引用自 KAMIKAZE!!!!!!：ditto, tried above methods, still doesn't work I fixed the problem. I found that Anti Virus Programs such as McAfee or Norton, etc. actually cause this problem and interfere with updates. I would try and try to start the game and would keep getting this error, then I would go into McAfee and turn off Real Time Scanning and run the game again and it would work perfectly. Then when it updates you just turn Real Time Scanning back on again and it works fine. This happens every time there is an update for the game and disabling Real Time Scanning and then re-enabling it works every time for me. Hope this helps.
