It sounds like you have a broken piece missing from the front of the top plate latch area. Look at this thread and see if you have the same problem. The solution to fix the problem was also discussed.

The door spring clip goes under the screw head where the door lid hinge fastens onto the rear of the top plate.
Hope this helps you.
