Need Help Urgent(Window Regulator)!!!

[NYC-X5]

Yesterday, as I was driving I heard a pop(broken clip or something) coming from one of the door, and there you go another failure window regulator. Is the front passenger door that cannot raise or lower the glass and is stuck in the bottom position. This morning when I was tearing the door down and got everything remove and just couldn't get the bottom two screws that holding the regulator and glass out. I plug in the window switch but it couldn't raise the plastic clip that hold the regulator a bit. And there is no way for me to remove the regulator without raise the glass up. How should I go about it. Really need help here.
