Need help removing door panel...

So I am trying to get the door panel off but I can't seem to get it. I took off the mirror controls, removed all the screws, removed the power window controls and the hidden screw behind them, removed all the screws for the 8" woofer but I still can't budge the door. And I can't seem to get the woofer out either. Am I missing something? Usually there are just some clips after the screws are out and the door just pops off. Can anyone provide some insight?

Thanks
 
I don't have my '05 Mustang yet, and so haven't messed with the door panels. My current car, though, has hook-type fasteners instead of those (very breakable) pop-type fasteners. After making sure all the screws are out, try lifting up on the door trim panel instead of pulling it away from the door.
 
Thanks for the tip but I have tried that already. My old car was like that too. I can feel there is just one thing holding it in place but I can't see what it is. I figure it is some hidden screw somewhere that I haven't found yet, that is why I was hoping someone had an easy answer.
