Just installed all the updates, PGmusic workers must have done quite a job ..

However a Q: With v 519 there's a track muting issue it seems.

Soloing a track clicking with Control & mouse works OK. But if you solo one Realtrack, with underscore for MIDI data, and export the solo-ed track's MIDI by dragging to the left upper corner's dropbox, you can only play this solo-ed track from then on, except Audio. All other RT's stay muted.

Un-muting all tracks with a right click on 'Master's Un Mute All Tracks function works though.

PS Kent, Windows 10 64bit LoL. F
