Might be late in this reply, but likely the tray in the trunk was dislodged (has happened to me several times)... it's a tight squeeze, but you can get your arm behind and under the collapsed roof, into the truck, and just re-seat the tray into the slots on either side..
Always have the car running while raising and lowering the top. And if sticks, hold the button a long time if necessary. It will eventually go. Check for anything snagged in the transfer system. Read the operating manual as well for proper use and care.
