Problem with wireless keyboard after update

Hi

I am using Modecom MC-7000 wireless keyboard and I have a problem with media buttons as play/pause, stop, vol up vol down etc.

Before October update all of this buttons was working correctly.

After october update, buttons stop working. I hoped that next updates will repair it but they doesnt. Now i am after december update and media buttons still didnt work.

Can i do anything with it?
