Can't Create character!

When I always try do make one it show a message with "Error creating character", I tried changing name and closing wow but nothing happened.
HELP ME.

stop seleceting new WoD hair style and you will be able to create the character, you will able to use those hair style at barber shop afterwards

assuming you downloaded the wotlk(new), some of the models are bugged, just keep randomizing your characters look till it lets you create it.
