what is the problem here?

Looking for group is only meant for finding others to play a game with. Offering to buy/sell/trade,etc. Is not allowed.

IF you see something like this use the report post function to send it to enforcement for review

Ok there are a few things you can try, first try
clearing the cache



Second, is there a HDD(harddrive) hooked up to the box, if so remove it(with the xbox turned OFF) and see if it helps if it does the your HDD is dying or you Gtag is messed up



Try and see if it does the same problem on a diffrent account/Gamertag



If those dont work(most likey they wont)
Delete and Re download your Gamertag, thats what i personally think the problem is

2 days later and I can sign in , but no matter what I try "This game is no longer available" I am totally fed up with this , there's no point whatsoever and no help from anywhere. There are so many messages saying the same
thing. I will find somewhere else to play games

I hope the appeal option is available for you, Khaliq.

Lastly, in case your suspension lasts 48 hours or less, it is not eligible for an appeal because the enforcement team usually takes this time to review your case.
