Crap, I myself didn't get it from there (didn't upload it myself), so I'm not sure if it's corrupted or not. Track 17 is Jiku no Tou he, right? Good track, unfortunately I forgot the site where I got it at this moment...I'll try to find it again.
Perhaps you should try downloading it again or something.
Found a place where you can download it (as well as the other OSTs). Haven't tried it myself.

I can't download part 2 from pokeplus...there's something wrong, apparently i need part 2 to extract the songs in between
