K70 RGB Birghtness help

I just got my K70 RGB, i installed the software and updated the firmware. I then am to use the keyboard but if i press any button it changes the brightness, also the brightness and windows keys do not work.

I have tried assignments but the work and i have deleted all lighting profiles but still the lighting changes brightness.

I am using a UK layout and a USB 3.0 connection.



Please help
