Put Astra Twin top Back Manually?

Hello .I used my Astra convertible last night, taking to roof off was not easy.
I started the program and it stop when the roof got into the boot . But never finished sealing up tight. The bits behind passenger section didn't go down. I want to put the roof back up but the book Opel Astra twin top has pictures but not good enough. and no instructions. Has anyone put the roof back and can they let me know?
