Yep, same issue. What's worse - is the fact that the keyboard itself can keep the settings perfectly fine (until it loses power), so if you configure lighting and then remove iTake from autolaunch so that it won't start again and reset your lighting - it "kinda" works, but it's terribly inconvenient (also you have to terminate iTake via task manager to exit it without reverting your profiles to default).
As far as I can tell - the iTake program just can't apply customized lightning properly. Same thing happens when you try e.g. exporting/importing profiles - it tries to apply a profile, but fails.
