I'm not entirely sure, it seems to have problems with multi factor authentication, but the last login problems have been ironed out in the latest stable. We know Amazon's working on something for (at least) US, they might be doing something more than expected.
In order to help you I need you to follow instructions here, that helps you enable debug logging, then from Amazon VOD connection settings set region to Germany, clear cookies and then try to sign in again.
