Installed on D:\bb - Band-in-a-Box 2019 UltraPAK Upgrade with RealBand

If I look in my Soloists folder (D:\bb\soloists) I have 4,150 items.

In my old version (I upgraded from version 2007 or something) I had some great guitar soloists, one of them was Jeff Lorber. Now in my Soloist dialog box the Jeff Lorber entry has "N/A" in front of it and I can't select it.

Additionally, when I go into "What add-ons do I have?" under Soloists I only have these listed:
"Soloist Disk Sets : 12 Andy Laverne Mainstream, 13 Andy Laverne Pentatonic"

I feel I'm missing something. Maybe I've not installed them all from the downloaded install files?
