CLK License plate lamp replacement trunk lid/lip removal problem!

[Johnny916]

I can't get the license plate lamp bulbs replaced because the service manual says there's only two screws that should be removed in order to remove the trunk lip/lid.. There's actually two screws and one screw in the middle that can't be removed..

So somebody tell me,what's the trick?? How do I get the middle screw that has no cross threads!?
