Game crashing

Hey guys,

I'm having my game often crash for me with the following error and it's getting really annoying. This happens mostly in Dalaran, I don't know who I'm bumping into. Any suggestions?

This application has encountered a critical error:

ERROR #134 (0x85100086) Fatal Condition
Program: D:\Games\World of Warcraft 3.3.5a (no install)\Wow.exe

Failed to read file world\expansion02\doodads\stormpeaks\scourge\orang escourgebubbles00.skin.

Debug Details:

[2] err=0 text=SFileReadFile - world\expansion02\doodads\stormpeaks\scourge\orang escourgebubbles00.skin - Data\lichking.MPQ
[1] err=0 text=ReadSectors/DecompressData failed
[0] err=0 text=ReadSectors/DecompressData failed

Most likely a corrupted file, redownload the game. Are you using updated models or standards ones?
