Nostalrius Begins - Quality wow vanilla realm (1.12)

Everytime (it seems) I select a new target that I have never selected before since I created that character, the game crashes giving me this error: http://puu.sh/hzfaJ/1516f66d05.png

"The instruction at '0x0059A00A' referenced at memory 0x05321000
The memory could not be 'read'. "

This is after a fresh installation without any addons whatsoever. Has anyone else had this problem, or know how to remedy it?

Greetings
