BF4 PC - Starts Windowed - Can't Click

[notenoughlube]

Just bought Battlefield 4 on Origin, never played a BF game before but I loved the lok of this game so I decided to purchase it. For some reason whenever I launch it, (through the website thing) it opens in a windowed mode, and I cannot click anything, it has all the deploy stuff but I can't click. I have the regular mouse icon too. I have tried to tab to it or spam click it etc. None of it works.

My nVidia Driver is 320.49, but I'm unable to update to R331, as nVidia always says the installation cannot continue.

Please help me ASAP as I desperately want to play this game.

Specs:

nVidia geForce GTX670M

16GB RAM

Windows 8

Intel core i7-3610QM, 2.30GHz

Did you try pressing the windows icon key and then click the game window?

If thats no use then try the folllowing and see if this helps:

-Try again to update your graphics driver.  http://www.nvidia.com/Download/Find.aspx?lang=en-us

Save it to your computer and try install as Admin (make sure anti-virus is disabled). 

If you still get error what exactly does it say?

-Update your Microsoft .NET framework.
