This is what Blizzard says :
Quote
We usually see this error if the game tried to read a bad game file somewhere. If you're using a CD, have you tried the CD-Less instructions from the patch notes yet? If that doesn't work or you're using the online installer, can you try reinstalling the game?
And yea, nn to make additional threads.
