Problem loading custom roster file

Hi,
Would really like to play as the Kings post Sabonis/Haliburton trade. Found a roster.db file from your mod forum that has that trade complete. I'm trying to start a league using the Custom Roster File option (db file is in the app/disk/setup_files folder), but after selecting this .db file, pressing the green continue button doesn't do anything-- I am able to click it, but to no avail. Works perfectly fine if I select the default start, etc. Is there something obvious that I'm doing wrong? Appreciate the help.
