when you delete patch.mpq it will just take you back to 2.0.0 and you will ned to download from 2.0.0 to 2.4.1 which is about 1000 MB the same thing happens when you delete WoW.exe
yeah, if your dumb enough to delete 2.3.3 patch and 2.3 to 2.3.3 patch 6):
i have to give you rep for that post man :>
