Hi, i bought an unmodded xbox360 yesterday and connected to live using created gamer profile and downloaded updates. I switched console off then later after a few hours when i tried to log into live it didnt connect after a lot of tries even tho network test passed. And then i wanted to play offline and i realised i couldnt access my profile (even with cable disconnected). I deleted the profile and wanted to create another offline one but it cant save the new profile    what is wrong with it???? i cant create an offline profile plus i cant connect and now i have no profile and cannot save ne games 

Please help

  HDD unplug one worked, thanks
