Why does microsoft train simulator crash on startup?

Hey, so I downloaded Microsoft Train Simulator (I'll call it MSTS for short :P) via torrent because its made by fucking microsoft! Can't trust it'll be a good game! But it crashed when I tried to run it! I defenetaly installed it correct, because theres nothing to do! (OK, heres what I did. 1.Mounted disk1 then started installer, then mounted disk 2 and finished installation, then restarted PC because it told me to) And I ran fine on my old PC that was windows Vista, this PC is windows 8, I dunno if thats the problem! I used troubleshoot compatability and ran it with Vista pack 2 and also tried XP pack 3 but it still didn't work! Keeps crashing! Any ideas?
