" This update does not need to be applied. It requires version 3.0.3.9183 of "WoW.exe", but you already have version 3.0.8.9464."
This is the message i get on my 2nd Account, this is after it goes through the motions for DLing the patch and installing it
I recall encountering something like it before when a patch arrived but cant recall what i did to fix it.
