Windows has this habit of making the newest device the default. Once you updated, Windows probably made the Kemper the default sound device. It did mine and I didnt even notice it since the Kemper plays thru my normal audio device.
1) Right click the speaker icon in your System Tray (right side of taskbar). Select Sound Settings.
2) Select your old device as the default Output and Input device.
Thanks for the help! 
I also didn't understand why צט PC goes crazy that the Kemper is on
