Hacking My GBA Music Converter won't stop freezing.

[PokeyStix]

I try to add some songs to the GBA Music Converter and it freezes. This happens all the time.

I don't have a Passcard 3, so I can't use Moonshell, I just want an actually helpful solution rather than "CONGRATS UR M3 IS DEAD GET A SIMPLY"

I have an M3 Lite Pro..

Please help.
