Problems with Concept BB

So today I was out and about checking for new TF toys, for the most part I didn't find anything except for a few new toys at a local Wal-Mart. So I found and bought a movie PAyload and Concept 09 BB. Once I got home I of course took them out of their boxes and transformed them. When I was trying to get Bumblebee back into his car mode his right side wheel/door section feel off... and then the screw came out. The screw is bent and it looks like it's stripped. Any idea if this can be fixed?
Also, I find this version of BB very difficult to get back into vehicle mode, any tips on how to do that effectivly?
