Hmm, I don't see an error on my side, can you make sure you are using the latest version of the addon and it's installed (I also just did another bug fix, so the latest addon is 2.1.2.) Also, you can open the dev console and see what the error reported is. Thanks for trying it out, I am sure there are some rough edges :)
