A few things to correct in the files that you uploaded.
* The Rigidbody is missing the Index files.
* The tank model has extra caterpillar next to the tank as well as some text floating in the air.
* The projectile model has one of the surfaced inside out.
* the file, explotion.zip is a corrupt file, can not be opened.
Do as Daniel suggested, compile the project with out the runtime files, this way we can just put thouse folders in the mail 3D Rad folder and it will run fine.
