I tried to play today and was met with this error:
This application has encountered a critical error:
ERROR #132 (0x85100084) Fatal Exception
Program: (insert drive directory here)\Wow.exe
Exception: 0xC0000005 (ACCESS_VIOLATION) at
0023:008D2412
The instruction at "0x008D2412 referenced memory at
"0x0000000",
The memory could not be "read"
Ive attempted to delete the .config file, the cache, as well as have redownloaded the WotLK files, but nothing works.
