from the instructions.txt file in the .zip:

  In Summary:

  a)      When a module has problens it isn't loaded into memory behaves
        like if it weren't there. Moreover, Blender will show an advice
        saying that the module doesn't exist.

I suspect this comes from Python's new handling of modules: if a
module fails to load, it is cleaned up completely and not left in a
broken state.


  b)      When a module is right can loaded into memory but if the module
        is already loaded it won't be loaded into memory again even if
        it has changed.

This is standard python behavior.  Once a module has imported
successfully, to reload it, you need to do a reload: 

import foo
reload( foo )
