XDJ-Aero only loads songs from laptop for 1 minute (solved)

Oke, so I got the XDJ-Aero because this looked to be a very simple and easy to use controller/ DJ system. After two full days of testing and trying stuff I officially give up.

I started with a USB hard drive which is working fine. Also a USB stick is working without any problems. Using my phone (Samsung Galaxy SII) and my laptop (HP Compaq 6820S with XP) is no go. 

Laptop:

I can connect to the XDJ wireless to Rekordbox without any problems. I can scroll through the songs and select a song to one of the players (music starts playing), but if I don't do anything for more than 1 minute Rekordbox tells me I'm unable to load the song. Looking into the forum this seems to be a unique problem, because it should either work or not. Even with the firewall completely off the problem still occurs.

Phone:

The problem with my phone is a lot easier. It just doesn’t work at all. I first connect to the wifi of the XDJ and then startup Rekordbox mobile. Looking at some Youtube movies all I have to do now is simply push the connect button and I should be ready to go.

All I get is the message: ‘please push the connection button that is located below the tree view of Devices pane of Rekordbox (Mac/Windows).’  And underneath that the wifi name of the XDJ.

I’m no expert on wireless systems and have no idea what to do. Please advise.
