Whenever i start up my wow ( in 64 bit 32 bit works fine somehow ) it starts up the game and it shows me the screen where i have to insert my username and password to login , it shows this screen for maybe 3 seconds and after that my wow crashes

Overall not that big of a deal since 32 bit works fine , but I got used to opening 64 bit wow and im using tmorph , couldnt find a tmorph for 32 bit so far

Hope someone could help me out with this ^^
Thanks
