i cant remember the protection scheme, but i would not be surprised if it a "combination" of different evils, that would fit into the picture.
the only thing i can tell you for sure is that i never installed it anywhere, and that this usually means that there 1. is no demo version, 2. i have not bought a copy, and 3. i had no alternative option to install it.

unfortunately in maxmsp file handling is an absolute mess, otherwise i would just build something better. i am huge fan of standalone organizing, sorting, archiving apps such as soundminer and it once had a good reputation when it came out.
