Please help!!!

So I'm making a mod for the game (which is in the same time a school project) and whenever I try to load the jbeam with or without the flexbodies the game shows me a little box and freezes the physics only for it and when I try to freeze the physics for everything the game puts it into one of the crash testing things. Please help fast this is a school project that has to be done by MONDAY!!! (All the pictures in the attachments)


BTW it worked on the old version of the game

 

Should have started your project sooner.

Open the console with the '~ key, next to '1' and post a screenshot of it. This will help us determine what the problem is.

 

My question is what console with what key and what 1

 

The game console with the keys on your keyboard.

 

OK, Here
