I'm trying to do the same, but having great difficulties setting it up.
I can set up individual position by entering them in, but I want to use a db that I already have, ie I want to import a PGN.
Every time I try, it fails, either not importing or importing just the initial setup.
A simple PGN as below fails.
Sometime, I get an error exception as well.
My method is to create a new repertoire, then add a folder and then import into that folder ( setting type to topic, not openings ).
I've also tried importing to the folder, that always fails.
Any advice useful since setting these position sup my hand is time-consuming.
Import via EPD is no available here, so it has to be via PGN.
Cheers
