Cant play online / multiplayer

I recently just activated my 30 days trial xbox live in the hope to enjoy halo 5 multiplayer. its a big mess
when i insert halo 5 cd, the game launch, then the “get more with gold” pop out non-stop even when i try to close it. Halo screen shows error with party chat because of xbox live service. i cant even play single player offline now because i cant get pass that obnoxious non ending “get more with gold” screen.

Ive try my xbox live service to play other multiplayer games ie forza horizon and gears of wars and its working well.

is halo down or something?

please assist
