error

[WOTLK] Since last update I can't log in my character that is located in outland. I get this:

Failed to read file World\Maps\Expansion01\Expansion01_29_31.adt.

Debug Details:

[2] err=0 text=SFileReadFile - World\Maps\Expansion01\Expansion01_29_31.adt - Data\patch.MPQ
[1] err=0 text=ReadSectors/DecompressData failed
[0] err=0 text=ReadSectors/DecompressData failed


Tried clearing, unchecking read-only on those folders, changing graphics,resolution and it is still happening. (WoW was downloaded from Warmane links.)
Any suggestions?..
