Skywriter Error

I have done 3 separate installs on two different pi's and still no go.'

I get this error :

Traceback (most recent call last):
File "test.py", line 2, in

File "/usr/local/lib/python2.7/dist-packages/skywriter.py", line 488, in

Any help would be much appreciated it. I am close to ditching it.
