...and the drivers window went POP

[SVXx2]

So I'm in the car, and decide to roll up the windows and turn on the A/C. All of a sudden, I hear a loud POP and the tinkling of glass. All windows are up, but when I try to operate the drivers window, I hear the motor, but the window doesn't move. Did the glass come off of the rails, and then get broken down in the door? If so, ideas for fixes?
