My Sims 3 Game won't download?

Hey, I've downloaded my game before but I haven't played it in awhile and now it won't download anymore. Each time I try to download it it says File:E:\ GameData\ Shared\ Packages\ FullBuild1.package and then Error: Data Error (cyclic redundancy check) I cant delete it out of the folder because it is not there in the Computer : C but it is on the disk and I can't delete that anyway. If you could please help me it would be the best. Thanks!
