If the CTRL+ALT+DEL didn't work, then you may have to perform a hard reset. Do you have your stuff backed up?
No, I can't either cause i can't get anything to work or get off the screen. But it doesn't matter
Below are the instructions for a Hard Reset. You will lose your data but it should fix your issue.
With your Motorola Droid still powered "Off," slide open the keyboard.
