When i try to do any script from test subdirectory I take something like this:
Traceback (most recent call last):
  File "D:\Utils\python\lib\site-packages\Pythonwin\pywin\framework\scriptutils.py", line 310, in RunScript
    exec codeObject in __main__.__dict__
  File "D:\temp\PyUIcvs\tests\test0.py", line 46, in ?
    run()
  File "D:\temp\PyUIcvs\tests\test0.py", line 13, in run
    core.init(*opts)
  File "D:\Utils\python\Lib\site-packages\pyui\core.py", line 57, in init
    from renderers.pygame2D import Pygame2D
  File "D:\Utils\python\Lib\site-packages\pyui\renderers\pygame2D.py", line 28, in ?
    class Pygame2D(pyui.core.RendererBase):
AttributeError: 'module' object has no attribute 'RendererBase'

What's wrong?
