Im working on a mass driver cannon for halo (it barely resembles the one from reach) its a turret, and im having trouble exporting it. i have it divided into several parts- a generator, the base, the drivers, and the barrel. i linked each part to a frame node, then linked the whole thing together and tried to export it, but it says To many actors in one scene, and Cannot export single model.

You have too many parent nodes, there should be one frame node, which should have everything linked below it, meaning any other nodes you used for animating should be linked to that. You sound like you linked all of the parts to separate frames, just link those to a "master" frame at the origin.
