I've installed the iSiloX application, but I can't figure it out how does one convert Watchtower Library CD to PDB format. Also, from the description, it's said that it loads PDB files, but then again after installation, I couldn't find a way to load the PDB files into the application. The application does something else or the description is wrong.
I've also located the website for the WatchTower Library CD, but there is no connection between them. If you can load the WatchTower Library CD app, access its Help section and check to see if it supports saving to PDB.
