If you can, boot into safe mode and back up the mandatory files you need. I hvae gotten that error a few times on the radio station computer at school and sometimes a simple reboot fixes it other times i need to do a complete system restore. I have never lost any data though, so it may be a good sign. I think people tend to overreact when they see that screen. Just pull the power and reboot. I hope it works out for you.
