EndreWhiteMane: Once it's installed you can choose whether to auto update games. What you have looks like a glitch, I'd kill it and try again.
BTW: I haven't used it for some time, didn't really see any advantage.
moonshineshadow: Yep, that is certainly nothing to do with updating the games. That is the client update. Seems like it is stuck somewhere. I'd kill the process and give it a new try.
Yep, you were both right. Once I restarted the process, the client looked the way it should... and began automatically updating some of the games.
And I can only feel relief at the fact that I uninstalled Witcher 2 beforehand.
As for the advantages. Neither do I, just wanted to try it out.
