Drivers window stuck in down position

[Multibeemer]

As it says in the subject line, the drivers window in our 03 4.4i is STUCK in the down position, but it seems to be a little different than other threads I've searched on this problem. I can jiggle it a little at the back, but it's really stuck at the front - no matter how hard I tug, I can't get it to budge.

I assume the regulator is toast, but I need to get the window out in order to replace the regulator. Ideally, I'd like to move it to the up position while waiting for a new regulator to arrive.

Has anyone had this particular problem? Any tricks to getting the window to come free? I can't even get a flashlight to shine on the area that's stuck to give me some ideas as to what I should do to get it loose. Should I remove the bolts holding the regulator to the door frame, or is this going to just make a bad situation worse? Thanks in advance.
