So idk why but for some reason after not using my xbox for a whole my battlefield multiplayer account isn't activated anymore, it says it on the side in the battlelog or whatever

I still have the activation code but when I try to redeem it again it's already been used. And it sucks cause it only shows like 1 or 2 game server

Is there any way to fix this?

you dont need a code to play online anymore.

You don't need the online pass.

You DO NEED to download about 13 gigs of updates to be able to play on all the servers.

How do I download the updates?

Go into the store from the main menu and there should be updates to download.
