First of all sorry if this is the wrong forum.
So after i installed the ptr today, played a bit and then closed it down. I was about to start it again but i didnt find any ptr folder or anything that have with ptr to do(didnt see any ptr folder b4 i started to play on the ptr either). Tried to install the ptr and got this message "The installer does not need to be applied. It requires a version of "Wow.exe" older than 4.0.0.12635, but you already have version 4.0.1.12941." Anyone else had this problem and know how to solve it?
