i bought bf3 from gamestop for PC a few days ago, after finally downloading it i had to download it on origin then update it which took a few hours, i'm guessing it was the back to karkand expansion but anyways once it was all downloaded i tried to launch campaign and it went to battlelog.So i clicked on campaign and it said it was initializing but it's been like that for a while now. so i tried multiplayer and still nothing. so i looked at my files and my origin game folder was in my SSD drive and i only use that hard drive for my OS but the folder was empty, that's because i downloaded bf3 in a different folder.I downloaded origin and BF3 on my external hard drive for portability . so i switched them around and put the BF3 files from my old folder into the origin game folder and put that folder into my origin folder and they're all on the external hard drive may i remind you, now i'm forced to re install the game. so hear is my question, if the re installation doesn't work, is their another solution to this ? also i looked around and for some reason my compatibility mode was on windows xp. would that have something to do with the problem as well ? and i also put it on run as adminstrator.
