I used to change my models alot, but then it got boring, so i deleted the Fix for Troll to Undead Models named WoWME.
But then randomly I wanted to change my troll model into a undead model, so i put the race conversion into my Data folder and i loaded WoW with the regular WoW instead of with the Fix, and then i immediately got a Critical Error.
After this happened i didnt care anymore about being Undead i just wanted to play. So i deleted the Patch-4 and Patch-5 from my Data folder. When i loaded WoW up again i got the critical error again, it keeps on doing it every time i try to play WoW.
Can someone please give me some tips on how to fix this?
