Hi - I keep getting client crashes. I've tried troubleshooting but haven't been able to fix. (ie. clearing cache)

I've never had such an enormous issue with this on any other private server, even when using the same client (3.3.5, downloaded from warmane, without draenei models)

ERROR #132 (0x85100084) Fatal Exception
Program: D:\downloads\World of Warcraft 3.3.5a (no install)\Wow.exe
Exception: 0xC0000005 (ACCESS_VIOLATION) at 0023:53DF7CB3

The instruction at "0x53DF7CB3" referenced memory at "0x00000018".
The memory could not be "read".

just wondering if anyone could offer some advice? thanks!
