Never mind, there was an issue in their file.  Please test but I will be revering my changes because it was an error in their file.  However, going forward, they have converted mlox to Python 3 now. So as they continue to develop things what will happen is if they ever break things so that the old 2.7.x version of mlox, the one I have in the current.mlox.zip wont work any more, then you will have to sort using the Utilities tab and running mlox as an external program.
