Every time I launch, settings reset

This worked for me:
go to the main folder
right click on the wow.exe file
compatibility
check "run this program as an administraror"
open the wow and configurate the client again
try to restart and see if it works

That works as a temporary fix, i've found that it's everytime i open the WOTLK client i have to open my TBC client in Admin the next time after that.

I don't know why they are creating this issue between eachother but its annoying.
