call of duty will work on single player but when I try to play multi player it says "This program did not close properly last time would you like to run it in safe mode"
When I click yes it kicks me off and it does the same when I click no can someone help me

have you tried checking to see if your firewall isn't blocking this game. that's usually the main culprit when it comes to pc games messing up in multiplayer.

Try running it normally (Say no to safe mode)

If not, it probably is your firewall.

try plugging some headphones into the mic in you pc it worked for me.
