Welcome to SevenForums!

-Did you tried unplug the devices, stop the computer and re-plug everything and restart the computer?
-Check the battery of each connected devices
-Does the light on the connected key still blinking?
-Run a full scan for malwares & virus
-Test on another computer if does works
-Then, if not go to the retailler ask and test the wireless/bluetooth key for an exchange.
