Trying to make new class but ERROR.

When i click on "New character" in characters list :


"This application has encountered a critical error:
ERROR #132 (0x85100084) Fatal Exception
Program:   D:World of Warcraft 1Wow.exe
Exception:   0xC0000005 (ACCESS_VIOLATION) at 0023:004E204F
The instruction at "0x004E204F" referenced memory at "0xFFFFFE9C".
The memory could not be "written".
WoWBuild: 12340"


What is the problem ?


EDIT: When i create that new class in DB then i join the game, i have another error when i press C (open inventory) :


This application has encountered a critical error:

How can i resolve these two errors ?

Okay so my first error is a problem with CharBaseInfo.dbc and i rly dont know why ... When i allow the new class to a race on that CharBaseInfo.dbc, the client crash when i go in "New characters" x_x
