I can't see anything on the marketplace, it tells me an error occured, every time I try to check it
when I'm on "home" there aren't any updates visible or trics and news stuff
what should I do to make it work again?
Have you tried updating GfW LIVE here?
[COLOR=Red]Games for Windows - LIVE : Support Documents[/COLOR]
yes, I had that one already, I'm going to run it again, see if it changes anything
EDIT: nope nothing changed, maybe a fail of windows live, and they're suffering from a huge bug of something
