Through meticulous tinkering and careful typing, I have managed to get this activated for you, I recommend not touching the activating/deactivating of it until further notice.
The issue is coming from the plugin itself, and code it tries to run on activation is making it choke. This is the same issue I already have documented and a hopeful fix worked out for, but I also have to go through chain of command to get releases out. Given that it's a bug that prevents use completely, I want to get this fix elevated and out the door.
Sadly, the issue tracker is in a private GitHub repo, so I can't link others to it to contribute.
Regardless, you're up and running for the moment.
