Blackscreen after start

[tomies]

Hy again,

today i tried to connect my Wiimote to the Pc and Dolphin.
in Windows the Wiimote is there also in Dolphin shows up "Connected to 1 Wiimotes"
But i dont get the conforming vibration and when i start the game i get the message that the Wiimote isnt conntected.
Several times ALT+F5 makes no difference.

I google around and find nothing usefull.

Thanks Tommy
