I have the same problem on my desktop computer. it just says done at the bottom of the screen and all I've got is the blue background. My wife's laptop it loads normally. I Just google nc4x4 and click the link to the forum. If I click on the link that is for nc4x4.com it will do the same thing.
I.E. meaning update? Have no idea. It came on both machines and has been updated when they tell me to. The laptop is about a year old, the desktop is three.
