Account: Faction Change Fatal Error

Hey there!
Bugtype: After i bought Faction Transfer from Shop, I logged in on my Account. I started customizing my new Horde champion, and when i clicked next i got this message: Faction change unavailable. I relogged and now every time i try to click on the small icon which i can faction change i get "Wow Fatal Erro #132" from wow as you can see in the print screens.
I already deleted WTF/CACHE files no use.:(
Please help me i don't have anymore points to spend.
Thank you for your time, have a nice day!
P.S. Sorry if i bothered you but i don't know whom to adress to:(
