Problem installing songpack DJMAX Collectors Edition(Stepmania 5 alpha2)

[Serephral]

Hey, I've just recently come back to Stepmania from a three year break. I've downloaded a couple of song packs and installed them without issues however the DJMAX Collectors Edition (http://www.stepmania.com/forums/show...ectors-Edition) is giving me some problems. When I started up Stepmania, it recognized the new songs and loaded them, and when I'm at the main screen it tells me I have 175 songs in 3 groups. When I go to choose my songs, I only have two groups with a total of 70 songs and no trace of the DJMAX songpack. As far as step files go, I don't have much of an idea as to what I'm doing so if you need more information just let me know and I'll make sure I post it, otherwise any help would be great, thanks!

Edit: Although it is said to be for Stepmania, the song folders contain .BME and .BMS files which seem to be for Beatmania. Also, rather than having just one music file, each song folder contains 200+ single sound files. Is there a way to convert these?
