[quote][b]Posted by:[/b] FogboundCorgi60 I got halo 2 pc but it said i used my cd key to many times, i got a new pc i can play multiplayer fine on my old pc but i cant register it on my new pc... what do? I really hope i don't have to buy a game i already bought just so that i can play it :( Is there a file i can copy from my old pc to my new one? Also... Is matchmaking broken? [/quote] 5 installs per CD key, feature to enhance gameplay Yes, you'll need a new copy There is no matchmaking. That's all there is to it. [Edited on 01.19.2012 4:29 PM PST]
