I get this error when I run a file using the FileGenerator:

---------------------------------------------------------------------------
RuntimeError                              Traceback (most recent call last)

/home/booncw/yade/YADEbA/lib/yade-bA/py/yade/__init__.py in generateSlot(self)
   120                         print 'BUG: Saving to memory slots
freezes Yade (cause unknown). Cross fingers.'
   121                 #print 'Will save to ',filename

--> 122                 self.generator.generate(filename)
   123                 if self.generatorAutoCheck:
   124                         O.load(filename)

RuntimeError: unregistered class



And when I run a script using python, I get this error:

Welcome to Yade bzr2440
TCP python prompt on localhost:9000, auth cookie `sduayc'
XMLRPC info provider on http://localhost:21000
Running script mindlin_test.py
Traceback (most recent call last):

   execfile(script,globals())

   O.saveTmp('Mindlin')
RuntimeError: unregistered class



Please help me. Anyone who has a clue. Haha.
