Looks like you are trying to import the .pyc file. Instead you should copy both the .py and the .pyc file preferably into your script directory ( depending on your Maya Version, from the respective 20xx directory in the .zip ), then import the .py file and run that - it will automatically use the contents of the .pyc file.
