Craig, I'm guessing you have already tried, but have you tried pulling the window up by hand as you wind it up ??? this will take a bit of pressure of the regulator or scissor depending where the problem is...
The window may have jumped out of it's side guide tracks as well maybe. If you remove the door handle and window crank as well as the door panel you should be able to see inside and see if this is the problem as well.
Good luck.
