when i want to play halo online by most servers are errors with = cd key invalidi typed the right key with installationwhat is this problem? and can i solve this?
you had better be using a CD you bought...second it could be that somehow your key code has been invalidated, or that key code is already being used, or the CD you bought was not a legal one.[Edited on 3/23/2006]
it was legal im surealready used? can i buy a new CD key?
Probably. But I'm not exactly sure though.Check the microsoft games/halo site for an email address or phone number to contact Microsoft help.[Edited on 3/23/2006]
