Wiimotes keep disconnecting at gamestart

[Pschirki]

Hello, idk what i made wrong, but after each gamestart there is a little yellow "Wiimote 1 disconnected" in the upper left corner of the game window

i have a real wiimote connected to my windows 10 PC by the Wireless Sensor DolphinBar in mode 4.

When i first had my wiimote synced, i was able to control Wii Sports and some wiiware games with the Wiimote, but after i had to watch the intro video from wii sports resort, i couldn't control any game yet because of this disconnections.
Any ideas?
