Maybe you two should actually have a look at the vmf he posted, instead of blabbering obvious and non essential things.

I see you use the prefab from ABS pack, but the actual track that you build separately is incomplete and cannot co-exist with the prefab. You need to put the ABS pack prefab into your level and start testing after its complete. It should work as it is, if you just copy the stuff over and link them as they are in prefab.
Though you picked the stage-payload version, so i think you should be better off starting with single stage one instead. Might be easier for you.
