Help with crash

Greetings, so it turns out as i was playing this evening my game just crashed suddenly when i got too close to the barrens, and now everytime i enter i'm in that same spot again and the game just keeps crashing as soon as it loads. I tried deleting the WTF, Interface and Cache folders but all that does is just make it take like, 1 second more to crash.
This is what pops up in WowError.exe
Failed to read file Textures\BakedNpcTextures\6ae9209e1b54e452ce0ba02f 5cac460a.blp.

I think your wow installation is corrupted.
