I have a k55 keyboard and have updated the CUE software and drivers several times to no avail.
When launching some sofware the application will not launch until I unplug the keyboard. This does not happen with any other keyboard.
There appears to be a solution on this thread but apparently I don't have permission to view it. If you can, could you copy/pasta the answer please.
