Hi. I just downloaded 748mb sized Medal of Honor Spearhead from Kazaa. When I try to extract the file, it says it can't read section #(whatever the number is). When I try to install the game, it says " Windows cannot find "Medal of Honor Allied Assault Spearhead_Code.exe. Make sure you typed the name correctly, and then try again". I click "ok" then another message like this comes out "The registration number was not correct. Installation cannot continue. Does anybody know how to fix this?
