DWI Not Reading Songs

[ultimame2]

When I downloaded some songs, they wouldn't work. I put them into the Directory: DWI/Songs/DDR Max 2. The songs were: Afronova from Nonstop Megamix (/Afronova/AFRONOVA__FROM_NONSTOP_MEGA.DWI; AFRONOVA__FROM_NONSTOP_MEGA.MP3; AFRONOVA__FROM_NONSTOP_MEGA.PNG; AFRONOVA__FROM_NONSTOP_MEGA2.PNG); Tsugaru Apple Mix (/Tsugaru/TSUGARU__APPLE_MIX_.DWI; TSUGARU__APPLE_MIX_.MP3; TSUGARU__APPLE_MIX_.PNG; TSUGARU__APPLE_MIX__BG.PNG); and Wild Rush From Nonstop Megamix (WILD_RUSH__FROM_NONSTOP_MEG.DWI; WILD_RUSH__FROM_NONSTOP_MEG.MP3; WILD_RUSH__FROM_NONSTOP_MEG.PNG; WILD_RUSH__FROM_NONSTOP_MEG2.PNG). I got these songs from http://www.ageofinsanity.com/dwis . Anyone know what's wrong?
