Have a service alert when trying to use xbox live.

The warranty on a second-hand Xbox console is void, and the purchaser assumes the risk for any previous modifications or unauthorized activity. Even if the console’s ownership has changed, the console may
still be subject to a ban. If you purchase a console that has been previously banned you will not be able to connect to Xbox Live, and the ban will not be lifted as a result of the change in ownership. We recommend customers who believe they have not committed
actions on the service to warrant a ban to contact previous owners or users of the console.

If you have purchased or intend to purchase a second-hand Xbox 360, you can check its current ban status by entering its serial number into the

Console Check Tool.

Hiya!

Paul from the Xbox Forums Team here to assist, it sounds like you're experiencing an issue with playing some games on the Xbox 360. I definitely understand how frustrating this issue can be. What I recommend doing whenever a Service Alert is active I recommend

The console may have been banned from using Xbox Live services.

This may have something to do with the current service alert. If you check here:
support.xbox.com/.../xbox-live-status you will see the live status (which is having a service alert) and when it is fixed. This happens now and then, though it is rare. Try again
when things are back to normal.
