PLEASE help me!

Every time I tried to log on destiny I get to the first section where I pick my character. Once I pick my character it takes a Pause... And then I get an error message saying that, " ATTENTION. You have lost connection with destiny servers. Your permission to access online multiplayer gameplay may have changed or your profile may have been signed in elsewhere. For more information, visit help.bungie.net I don't know why is saying this no one else has my password or username or email and I have paid all my dues I've even pre ordered the taken king and I have every other update. Can someone please explain to me why I cannot play the game I have paid for and paying for the plus network connectivity and still don't have acces to Destiny gameplay only. However it works perfectly with any other game it seems like I'm being either blocked or hacked??? Someone who works for Bungie or Playstation 4 someone who knows about this message please explain to me why am I having this problem? PLEASE. Is it doesn't get resolved I'm going to start posting this on youtube and telling the world why I'm getting ripped off basically.
