Thats the message I get when I try to download the patch. The same thing happened when I tried to download the patch for 3.3, I couldnt figure it out.. so I uninstalled, and reinstalled everything from disc. Now I have the same problem again. I would hate to think I have to do it again. I dont play on the PTR, I dont alter my game in anyway except for a couple raiding addons. I dont know what to do, just looking for a tip that might help.
