When ever I try to go online with condition Zero, It just takes me to a black screen, and crashes. My system meets the requirments and i have even looked for patches.

do you have a firewall software set up? if so, you'll need to specify access for CZ in the actual firewall program.

In case you don't already know, the in-game link to online servers no longer works. They used to link to WON servers but online play has switched to Steam. You need to go to Steampowered.com (http://www.steampowered.com/) and setup an account.

I use steam, and my firewall allows cz and steam
