i got a big problem with my cherry keyboard
Cherry - eVolution SIRIUS XT Wireless MultiMedia Desktop
all hotkeys worked properly until my system crashed due to some OC. now all other keys work but hotkeys (play, mute, forward, backward, volume up, volume down, calculator, e-mail, home and sleep) which are all hotkeys my keyboard has. they were all global setted so i was able to skip tracks while musicplayer was in tray on default settings.
i tried to reinstall windows plug&play-drivers but it doesn't help. please help, if you can
