Have you made sure you've downloaded the latest version of their
CUE software engine with v1.16.42? Often times you'll need to uninstall and reinstall some software's in order for the system to maintain full functionality.
I must ask though, what are your full system's specs inclusive of your OS? Have you made sure your BIOS and chipset/USB drivers are up to date? Speaking of up to date, have you tried creating a lighting profile of your own and seeing if that takes hold? Paul(from Newegg and Paul'sHardware) did state that the new keyboards were acting up with profiles and the software overall. It may be something worth
contacting Corsair about it as well.
