i try the demo and i want to play online but its said matchline is offline?

Are you sure the demo you're playing enables you to play the online game mode? I'll be honest with you - I only have the game, I never played the demo itself - but sometimes the demos don't grant you access to all game modes. You need to check out if it does give you access or not.

He is trying to play the online demo, so of course it's possible to play online with it. The thing is though, that Ubisoft might have closed the online access for the demo.

Oh, ok then, I honestly did not know that, my mistake then, sorry.
