Phenom 2 x4 965
Asus Crosshair IV Formula
Still running my 9800GT until I decide on which newer card to get (too many choices)
I have not played WoW in months but I figured I would check out Cata (probably a bad productivity choice). I copied my WoW folder from my portable HDD and updated it to Cata (including 4.01 patch = 10gig update, ouch) and now when I try to log in, the game simply closes. It will hang for just a moment and then closes to desktop.
I run Comodo Internet Security anti-virus, and WoW.exe is run as an administrator and is on the trusted files list.
If the repair doesn't work then I'd forgo the attempt at copying the files & just do a complete reinstall. I've never heard of anyone "copying" the WoW folder instead of installing it & have a strong feeling that this may be corrupting the file in some way. As stated by Mokomaki, it will be a pain without the games disks, but would be worthwhile.
