Hi Christy and welcome to the forums.
TDK has stopped support for this but all is not lost as it would appear it’s actually made by Casio.
There’s also a Casio CW-100 and it seems they’re identical.
So try the software here and see if this is what you’re after.
You can also get the manual for the software here.
