Alright, I've tried every way to de-patch my client's version to 2.0.0 from 3.1.3 but its pretty much impossible.
So, I installed WoW again via the WoW Installer supplied by Blizzard. Apparently the Installer downloads the game with a automatic 3.0.0 patch. So, I looked around for my old classic disks since installing the game from the disks wont get automatic patches since the installation on it is client-side, which I just had the disks a week ago, but I lost them. I just need a WoW client thats 2.X.X or down so I can use Noggit.
Does anyone have an idea on how to get a 2.X.X client that works? :P
Thanks in advance.
