Did you press the, “Reactivate button” in webconf? (I don’t see that button - maybe because I haven’t yet installed my licensed version.)
I followed the instructions in webconf to update to PT7.0.5 Stage Trial, rebooted then pressed the button, “Update Presets” on the webconf page http://zynthian.local/sw-pianoteq. I can now see the PT7 presets. Later today I should have chosen my instrument packs and will install the licensed version.
