Games will not launch?

[moirane]

Hi everyone,
Thanks in advance for any ideas on what could be wrong...

About a week or so back almost all of my games stopped launching, when I press the tile to open one it will say "loading" for a few seconds then go back to the xbox live screen.

I am hoping that the imminent Mango update might correct whatevers wrong with my focus but figured I would see if anyone else has had this happen and what they may have done to solve?

Any ideas?

Thanks!

Kevin
