cant launch bo2 multiplayer

[JOHNWICKS]

when I try to launch bo2 multiplayer it starts to boot but doesn't start the game when I changed the resolution
zombies and mw3 (iw3) works fine and everything but when I change the resolution the game doesn't start

JOHNWICKS are you talking about your screen resolution settings in windows? Which resolution works and which one doesn't?
I assume it's just showing a blank screen when you're trying to start it?
When it does that try tabbing out to the console window that opens behind it and executing

vid_restart

in that console window.

Dss0 sorry for replying late yeah when I start the game it just shows a blank screen
