Error when installing menu. TypeError: load() missing 1 required positional argument: 'Loader'

[futuremotiondev]

Getting the following error when installing a menu:

Traceback (most recent call last): File "C:\Tools\Context Menu Maker\main.py", line 12, in <module> condocp = ContextDocParser(open(sys.argv[1],'r'),os.path.realpath(__file__)) File "C:\Tools\Context Menu Maker\contextdocparser.py", line 13, in __init__ self.documentObject = yaml.load(document) TypeError: load() missing 1 required positional argument: 'Loader'

Had to install pyyaml and win32api as well beforehand.

Not sure how to proceed here.
