CT2 Will Not work

OK, I have reg by the way, I tried to log on and it said my account was inactive...Anyway I downloaded Crazi Taxi 2 and the file was zipped, then rar'ed so I gort down to the brass and it was a CDI (or CDJ) I can't tell. Anyway, I was going to use Disc Juggler 3 and it said it was an audio file, so I figured I would convert to ISO or NRG file, Nero would not burn it, said incorrect paremeters and so I figured I would use Easy CD creator 4.01. Well, it burned it, I set it to track at once because there were 2 tracks (I assume a boot and the main file) anyway, it will not run, so I downloaded and ran the Utopia boot program, still will not run...JEEEZ, What am I doing wrong?
