Been trying to reinstall game after a hiatus and im having trouble getting the patches after i've downloaded the game files. usually stops at around 74% of the 3.3.0a patch saying;

The patch "base\signaturefile" could not be applied. (Invalid source file size: expected 3047911, actual 3131378.) If this problem persists, you may be able to solve it by uninstalling and then reinstalling the game. If you are unable to correct this problem, please contact Blizzard Technical Support. (BNUpdate::PTCApply)

I tried clearing all the old patches on my comp but i guess i could have missed some.

On a mac if it matters.

Thanks in advance.

Hello Harke,


Either the patch is corrupted or being blocked by either a 3rd party security program like PeerGuardian or Norton, etc. or a network security system. If you are using a wireless connection then it's probably the first issue.
