Login Screen won't come up

Patcher comes up no problem; however when i click "Launch" on the patcher screen nothing happens and the game closes. it removes itself from the task manager and all. I usually have to go through this process for about 30 minutes to get the game to launch. I have tried deleting everything as well as reinstalling and restarting my computer many times. Any thoughts on what could be going on? I should also not that I am running it as administrator and on Windows 7 64 bit.
