Missing .exe

[Boogieman]

After the patch today the .exe is gone from both wow folders the launcher come up but when i hit the play button nothing happens and i tried to let hotkeynet launch them as usual without the launcher just from the .exe and they all came up and went right away now HKN does nothing when i hit the hotkey to launch and rename


EDIT : this is the message from hotkeynet

<Run "C:\program files\World of Warcraft\wow.exe"> failed: Operating system CreateProcess function failed; Windows reports system error 5, "Access is denied."
