Just received my Sansa Connect and was about to charge it for the first time using the AC Adapter.  I admit I'm not the most technologically advanced person but obviously something is missing here, there is no way the prongs are long enough to fit into any wall plug.  They're not even really prongs, just 2 little metal loop things.  There is a button that says "push" and it appears something fits into the adapter over the little loop things.  Am I missing a part or something??
