Can't open WoW.exe for Frostwolf

Hi, I downloaded the full torrent client for Mists of Pandaria, but I cannot open WoW.exe. When I try, there will be a long wait where nothing happens, until this error message pops up: http://imgur.com/DLX8ZlE

I have donated for Frostwolf items and not being able to log in is very frustrating. Can I have advice on how to fix this?

1) Restart your PC
2) close your Torrent client and move your WoW folder away from your Torrent's download destination
3) now right click on WoW folder> Properties> remove "read-only"

Thanks, skull. But the same error still appears even after doing all 3. Any other advice?

yes, do the same but better this time because those 3 Steps should fix your problem.
Try to move the folder on your desktop

move wow.exe to your desktop and then open it from there

it worked for me
