Hi Paul,
The Python scripts in the SDK are based on Python 2.7. As you say, to run them in Python 3.3, you need to make some syntax changes to the scripts in the SDK. For example, you probably noticed that you have to change the Python 2.7 Print statements to the Python 3.3 Print commands, which, if I remember correctly, involves adding parentheses to surround the print string. Alternatively, you could set up your system to use Python 2.7 for this application.
The problem you describe seems to be with the file path for the SSC library file (.dll). One thing you could try would be to put the library file for your system in the same folder as your Python script files and then changing the file path and name in the PySSC class definition to the file location.
It does take a little trial and error to get the SSC API set up to work on your system, so don't give up! If anyone else has suggestions, please feel free to chime in.
Best regards,
Paul G.
