We both have the same issue. The launcher says game is up to date, click play, the launcher loads, disappears as normal, WOW doesn't launch and the launcher simply reappears.
The friend from skype lives completely across the country. And there are alot of views/posts about this. 500 players didn't suddenly lose administration access to their wow folder. Would appreciate a legitimate response from a blizzard tech. Atleast tell us you know there is an issue and that it will be fixed.
I have tried logging in with the 32 and 64 bit version of wow. I have tried logging in via the wow.exe and skipping the launcher (this simply starts the launcher).
There is no repair tool. I drug the latest patch file out of the folder, launched wow in an attempt to redownload the patch (incase of some random corruption) and then login the game normally, this was unsuccessful, the launcher didn't even notice it needed to redownload the latest patch.
I have taken a look at other posts, I have played this game seven years, please don't link me some BS "FAQ Tech support" link from blizzard.com, please don't tell me something completely retarded like "reinstall the game it will work" or "its client side, try logging into a different windows user account" or "you need to take permission of the wow folder" these are all ridiculous fixes that, aside from reinstall, MIGHT work for one in ten thousand users if by some random anomaly their issue pertains to the specified fix.
Real post. Real answer please.
