Thanks guys. I fixed it by downloading the .exe from the topic Spawn linked to, here

That sucks though, because using this compatability setting means the game won't create the GTA San Andreas User Files directory in Documents, which means it won't be able to save or scan / play tracks for the User Track Player.

And it doesn't look like SAMP will work with any other setting, so you cannot play SAMP right now with User Tracks, which sucks ass.
