Motocross Madness 2

Last night I wanted to play MCM2, but my CD was scratched and wouldn’t install. I had burned the program files copy to CD once before, but when I tried using it, it told me there was an installation error. I attempted to install from CD, hoping it would fix any problems, but it seems the files that wont install are the ones I needed. I then downloaded a CD image of it.. (I wont say where I got that ;)) but my DVD burner isn’t working.
So how am I supposed to use it? Well I found a free extraction program called [url=http://www.extractnow.com/]ExtractNow[/url] that worked quite well. After extracting it I put the CD in and opened the downloaded install file. (I put the disk in because I didn’t want to confuse the machine in any way..)
Well I hit play, and it worked fine other than my downloaded bikes and riders.. but I backed them up anyway. My tracks are still there, and the game itself works fine.
