Hoe can I remove wrinkles from my DA-Lite projector screen? - fixed projector screen in canada

I have recently moved, and makes my Da-Lite Screen 92inch landlines.
He rolled in a tube, but it seems the weight when the tube was the right cause
Fold the lower half of the screen.

My question is anyone know how to remove wrinkles without damaging the screen?
The screen can be pressed or somthing?

Any advice would be very grateful.

Thank you,
