Xbox live gold - do you own this game or app?

All those games have been updated?

Try powercycling your console by holding down its powerbutton for 10 seconds

A hard restart would be to hold the power button on the Xbox for 10 seconds. If that doesn’t work, then you might want to try to reset the whole console. A hard restart doesn’t erase any data, but resetting the console will.

If you have the games downloaded and not on disc, you have to use the profile that purchased the games, unless the profile that purchased the games has that Xbox as its home Xbox. If you have the games as disc, you might want to try a hard restart,
or check service issues to see if its a problem with the servers, and not the console itself.

Thanks for your reply vTL Gerninator, all games are on disc but when inserted nothing loads, we just get the error message quoted before.

wont a hard reset erase everything?
