Dometic 13,500 AC ceiling cover.

How do I get the ceiling cover off? I pulled every screw I could find, including two in the middle. The cover still won't budge.
It is loose on both ends, but something is still holding it tight.

Did you remove the other two screws in the center?

[Matt Kline]

If I remember correctly it was two at each end and two in the center. Then we tried but something was still holding it in the middle.
