I dont really know anything about cockpit editing, however----

If you just want to move a msh then do this in the *.him file.
This file defines the position and orientation of all the msh objects.
There is a good Hier.him tutorial

If you are exporting a msh the most common problem I have is texture assignments.

Look in your original msh file and check the number of materials assigned.
Ensure that the same number of materials are assigned in your new msh -- and that they are in the same order ( order error wont prevent it loading).
