An update: I heard straight back from Jesse Yeager at compulsivecode, assuring me that nothing has changed except the name, so I tried downloading it again. Last time, I double clicked the zip file and somehow NCH installed itself and opened up offering to convert anything to a zipfile but without bothering to unzip anything, so this time I extracted the .exe manually and everything works just as I wanted
So back to the old faithful, and
it's free!
