I think I am having the same issue. I have had my K-100 keyboard and Nightsword mouse connected through a USB switcher for over a year without issue. All of a sudden this morning I turned my computer on (after the most recent icue update) and icue immediately crashes. Every subsequent restart of icue crashes as well. I have tried doing a repair with icue and while it says "repaired" the issue persists.
I am going to try and direct connect the keyboard/mouse to my PC to see if it is indeed the switcher being the "issue" but if everything was working and only an icue update being the one that messed this up, I won't be too happy as I run my PC and work laptop and would REALLY not like to have to get a second keyboard and mouse just to make up for Icue's monkey wrench breaking something that was working just fine.
