Launcher not working

Hi there. As of Saturday morning, I have been unable to get passed the Crossfire Launcher screen, and I don't understand why. I go to run Crossfire, it brings up the launcher (the popup window with the buttons Register and Start), I click start, as usual. Then the Start button (which is green before you press it) turns orange as if I clicked it, but nothing happens. Then after about 10 seconds, it will tell me that cf launcher is not responding, and to either wait for a response or close it. Then when I try again, it says "patcher is already running) so then I have to close using task manager just to try again.

I have no idea whats causing this. If I can get a logical response and solution from someone, I would be very much grateful, as I have already missed my ocg match last night, I do not want to miss tonight's as well. Thanks.
