Mailchimp connector not working

So, haven't worked with the Mailchimp Content Pack in the Service, but Content Packs in the Service and the Connector in the Desktop are two very different things. The Service Content Packs generally come with a manipulated data set, reports and a dashboard. When I say manipulated, what I mean is that you are not pulling the raw data, but rather someone has worked on and modeled the data, created measures, calculated columns and the like. The yellow star means that it is new. Not sure why it would be greyed out other than perhaps there is a problem connecting to and getting the data from Mailchimp.

When you are using the connector in the Desktop, you are essentially pulling the raw data. So, you have to do the manipulation of the data, expand tables, records and the like. Then, you have to create your own reports and dashboards. So, no, you will not get automagical reports when you use the Desktop connectors.
