Trouble with Xbox live

I just bought a Xbox and the game Modern Warfare 2. I am not sure how to fully use everything but last time I checked it said I have Xbox Live Silver, but when I try to play online Xbox modern warfare 2 is just says "The current profile is not allowed
to play on Xbox Live" then brings me to the login page where it forced me to log into my account, then when I try to play online again it does the same exact thing, anyone know why?

Can I still use my live on Xbox 360

I'm having trouble connecting to live with Xbox 360. I have no trouble with live on Xbox One. Are they discontinuing live 360 at some point?

In order to play multiplayer, etc over Xbox Live you'll need a Gold Membership. The reason you're seeing that message is because your account is currently a Silver Member, so you aren't able to join multiplayer matches and such. For more info on Xbox Live
and Xbox Live Gold, check out the
Xbox Live page.

 

As Tripp has said, you need a Gold XBL Membership for on-line gameplay.
