The new release is in the plugin store: http://www.indigodomo.com/pluginstore/77/
MyQ has deprecated V4 of their API. If you're getting plugin failures, that's why. This new plugin release supports the new V5 API.
However:
You MUST be using the MyQ mobile app. If you're still using the Craftsman app (and probably others), your login for that app will not work. Create an account with the MyQ app, get your openers working with that app, then install and configure the plugin.
You MUST edit your opener devices (in Indigo client) and reselect the appropriate opener. The device IDs changed between the API versions, and the plugin can't fix that on it's own.
Otherwise, it should just work.
