PTCGO: Black screen on load up

Hey guys, need help. The game was working fine until my computer updated a couple of days ago, now when I load up the game, soundwise everything is fine, I can hear the startup sounds and the "whoosing" when i put my cursor over an option on the login screen, the problem is that I can see anything, all i get is a black screen, same with the refresher program. I have tried completely deleting everything about the game and re-installing, restarted my computer, and couldn't find an solution on-line, so I need help, much obliged!

Try reinstalling your video drivers and make sure the system BIOS is up to date as well.

ok guys fixed it and thanks for your help, I just rolled back my windows update and it's working fine now
