Shipset script problems

when ever i use a custom shipset in a BM game they sit there doing nothing after having built some sat's and mine's, i've deduced this has to be something todo with the scripts. i've copyed over scripts from similiar races within the BM mod, and i think this is whats broken them. i dont really wanna use the stock scripts that come with them as their not really tuned to BM.
cheers
