New Release: Problems with widget

Hello,
Today I installed 3.0 Software on my Pc. I checked if all is working, fine.
Then i connected via network to a second Pc where the visualizer is
installed. The new Software found the correct IP address by itself..wow!
Both played perfect together.
Then i unplugged the second Pc and changeover to normal settings:
Pc with Faderpanel, hog keyboard 2 Elo touch and Single DMX Widget:
The hog keyboard dont work from the start like with last Release 2.6
The dmx Widget dont work anymore. Only the link led is on.
Also in the control panel there is no more widget configuration available.
So what can i do?
