Hardware Brawl Song Maker GUI 1.5 won't work?

[saison]

I've been attempting to use it, but every time I try to add a mp3 or a wav file it will just give me an unhandled exception error.

And I do have .NET Framework 3.5 SP1

It works fine for me. Remember. You have to put it in their correct place and rename it to the same name for the song.

And of course. Use FilePatcher 3.5.1 (it works too for USB).

Well, I mean when I try to add to the queue it will just give me the Unhandled Exception error D:
