My problem is solved, thx for the support.
What i did. I opened the dmxsoft site en registered the dmx fun. Make sure the dmx fun is connected before openening the site. Open the sut program. Synchronise. Then leave the dmx fun connected and open daslight4 beta. And it works. The dmx fun must always be connected to the pc before opening any program. Also i have noticed that with some internet connections it doesn't work. Maybe something in the firewall settings , intried it at work without result, i did the exact same procedure at home, it took 5mins and it worked.
