Cannot open my sheet music?

[itstehchibiness]

Well, I downloaded the only sheet music thats avaliable for secret of mana, and when I try to open it in adobe reader, as it is the only program that supports...er...  opening sheet music, it says basically that either the file is corrupted, or it is not compatible. Either one of the two.
So, I am pretty sure its not compatible, would anyone know how to make it compatible? or are there any other programs i could download to open up this sheet music from?

I am not a computer technician T_T;;; unfortunately.

Help would be greatly appreciated!!

This site uses Finale, meaning the files are .mus, not .pdf.

Try using Finale Reader to open the files.
