broken forever screen pin

One of the pins that holds up the screen in my Forever Door has broken off. As a result, I am unable to lower the screen. I am also unable to raise the window because the screen is covering the mechanism that releases the window so that it could be raised. Is there a way to lower, or remove, the screen so that I can access the window mechanism to raise it?

Re: Post #D47324 ... after trying to find a solution to this problem at Lowes, Home Depot and two local window and door businesses, the friend, for whom I had submitted this question, came home and simply stuck a screwdriver in between the track and the screen and the screen immediately dropped. She then was able to access the window mechanism. I'm not sure how the screwdriver solved the problem ... I guess, similarly to the way unplugging a computer will fix certain computer issues. Nonetheless, the problem is solved ... until she could purchase and install a new door. Thanks for getting back to me/us!
