"Sorry this console has already been registered to a different account" PROBLEM *UPDATE*

Dear Xbox community,
Yesterday, one of my friends sent me an invite to the Xbox One Preview Program. I received a message from the Xbox Live team with instructions on how to download the special preview app. 
Here is where my problems began. 
I have two accounts on my Xbox, my main account and my brother’s. When I opened the app I pressed ’Join’ with my main profile (Gamertag: Stratoulis89) and the app displayed a message saying: “You’ ll get a service message on your Xbox One soon with more info.
Opening the app today got the following message: "Sorry this console has already been registered to a different account". I deleted my brother's account and I reinstalled the app. I also cleared the cache of my console and still I’m getting the same message. 
Any help would be very much appreciated.

P.S. Here is an image showing the latest message from Preview App.
