Python error trying to run phoenix miner with phatk kernel in Windows 7

[karak]

Traceback (most recent call last):
  File "phoenix.py", line 123, in <module>
  File "Miner.pyc", line 76, in start
  File "phoenix.py", line 112, in makeKernel
  File "kernels\phatk\__init__.py", line 180, in __init__
    lambda x,y: self.size * 1 << self.loopExponent)
  File "QueueReader.pyc", line 40, in __init__
AttributeError: 'CoreInterface' object has no attribute 'addCore'


Sadly I don't know python - any clues?
