went to play BC2 today but for some reason i cant play the single player campaign. i let it install the new updates before i played it, but when i click on resume game i get the "map" screen that says loading but then it gives me an error message saying: disk cannot be found, please insert a disk into harddrive/hd2 ( or something along those lines). i can play online multiplayer just not the campaign, yet it was working last week before i had the update. also when i installed it i told it to use online authentication so i dont have to have the disk in, but i have put in the disc just to make sure this somehow hasnt changed i tried playing it with the disk in but same error again. my computer is authorized and ive tried de-authorizing it to then reauthorize but it doesnt seem to recognise i have de-authorized so that solution didnt help at all. anyone else having/had this problem? anyone have any solutions?
