Thanks for reporting this. 2.1.5 should be available in a few minutes. If it doesn't show up for upgrade, just deactivate/delete and re-install the plugin. It should retain your settings.
Can't believe I didn't think of that possibility or test for it before.. the plugin has gone through some major and rapid updates since it was released a few weeks ago, and I just overlooked testing of that.
Please let me know if 2.1.5 fixes the issue.
