Call of Duty World at War on XBOX multiplyer

First of all: You don't set up Xbox Live for Call Of Duty WaW, you set it up for everything, Netflix, any games, movie rental etc.

But you simply click one of the advertisements of Xbox Live on the Xbox Dashboard, and follow the steps, which are very simple ones.

If you get problems with the registration, contact the Xbosx/Microsoft support team. :)

Hacking in any way is illegal. If he is getting hacked, change his Xbox live account password, and do not play call of duty world at war until further notice.

Dashboard or restart your system. That is a glitch that sometimes happens. It's nothing you did, but rather the Activision servers sorta messing up.

Your score is probably on Treyarch's servers and won't be reset, but maybe deleting your game save will reset it. WARNING: You will loose any progress you have made in the campaign, but you'll still keep your achievements.
To delete the save, go to the SYSTEM tab all the way right on the dashboard, Choose memory, then Games, then pick Call of Duty WaW, then pick delete. Look at any of the other folders and delete anything related to CoD World at War. Hopefully this will reset your score online.

check playing with this disc on any other Xbox 360 connected to live, ideally the disc should not have problem since the problem you are facing could be with saving or downloading of the specific update required to play game online on xbox live which is mostly related to updated playlists.

If it still does not work, try erasing the saves for this particular game from your Xbox 360 HDD in case you are okay to forego the game progress / XP gained for the offline campaign play.

call of duty has a history of being a console killer, if your xbox 360 version is older, your console engine might not be able to keep up with this kind of game, I had an xbox 360 b4 and same thing happened it plays on other games but wont play with call of duty. It also happened to my ps3, what I did was I updated my firmware version for both console. Now both consoles works with call of duty. Give it a try. Thanks

turn your xbox on and make sure it has the red rings then wrap a towel around thexbox make sure its completely covered leave it like that for an hour and the problem should be fixed

you need to contact your ISP to fix it..
The issue is already on the telephone line.
