So i went to the WoW website and dl'd the ptr client, i run what the client has and i run the blizzard updater that was in the folder that was download. Shortly after i get an error saying: "World of Warcraft could not be found. Please make sure the game is properly installed." Although on my comp i obviously have wow and it is still playable on all of my toons on live. Do i need to reinstall wow? Or is there any way to fix this? Thanks!
