Downloaded **** revolution for Borderlands when it was the deal of the week a while back, and never played it. Today I finally got around to it and when It started it said "some downloadable content is corrupted and cannot be used." Now I have all four DLCs, so I deleted all of them, cleared system cache and re-downloaded. The three others work just fine, and I've deleted and re-downloaded DLC 4 as well as clearing the system cache to re-download the updates three times and still no dice.. Suggestions?
