Hi all, i'm hoping someone can help me with the roccat iszu software as i just bought this keyboard but am unable to set it up. Basically if i try and change the key shortcuts, they show on the software but just stay as the default function. For example if i try and change M1 to even shift+2 it still functions as shift+1. I have pressed apply and have switched to the right profile on the keyboard. If i shut the software down and open it back up it will say M1 is shift+2 but it still works as shift+1. this happens with all the keys i try and change. if anyone could help id be very grateful as i cant find any manuals or other information! The manual on the roccat website just links to a quick install guide which is useless.
