The engine is stuck! Regardless of what gear the trans is in (besides neutral if you call that a gear) nothing is going to turn over with the clutch engaged, unless you can get the engine unstuck.
The only things I can think of are that you either have the tranny in gear and you are not getting it into neutral. And/or you may have two gears engaged at once. And/or you have a tranny frozen too. What did your tranny oil look like when you drained it? Any water whatsoever in the oil?
You are just going to have to figure out where neutral is, and also if the tranny is stuck too.
Do you have any friends or Stovebolters with more mechanical background that live close to you, that may be able to take a look for you?
