Hi @SoccerArenaApp,
It sounds like you are missing the adapter for Millennial Media. The MoPub full SDK includes built-in support for Millennial Media. However, Millennial Media has deprecated support for Ant/Eclipse, so migrating users should use the MoPub Android base SDK and follow Millennial’s Ant/Eclipse Integration Guide.
If you are still having trouble, please reach out to the Support Team at support@mopub.com with the logs you provided, your account username, ad unit ID and any additional clarifying information so they can help you.
Thanks!
