Not sure what fixed it, but I did everything on the list again, full reinstall and disabled anti'virus (which I didn't do before) and now it's loading. Thanks for your help!
Hello, I deleted the file as instructed. The launcher then did open wow, but once logged in said 'game version incorrect' and asked if I would like to open in 32 bit mode. I'd click yes and it would restart wow and then say the same thing. Please advise. Thank you.
