OMEN004'S PROFILE

Hey everyone I'm new to the site and was hoping someone might help me out. I've downloaded several games and for some reason some games music files don't seem to play. I have downloaded rpg maker games in the past and had a similar problem as well. I currently have about 30 games total, several of which have no working music but most work just fine. I also have rpg maker VX installed on my computer, its the trial version (as I have yet to decide whether I should spend the 60 bucks or not). Also I'm running windows vista. Any help would be greatly appreciated, games just aren't as fun when they're quiet!
