Hitman Contracts Torrent File?

[dirtyrottenimbecile]

Hi all, i havent been able to find any answers so i thought i would come here. I just downloaded Hitman Contracts from a bit torrent but dont know how to install/play or copy it onto cd. It came in to folders CD1 and Cd2 and there was a MSInfor Document. the files inside the folders are namedrzr-hmca.001, rzrhmca.002, rzrhmca.003 etc. I got told to join these together or something using hjsplit which i did but couldnt or didnt know what to do after doing that, or if that was the right thing to do or not. If anyone could please help me, i would really appreciate it. Thanks Brett
