Curiously, PSP Master Q2 scans in DP 9.12 for Windows as "has serious problems and will not be loaded".

It works fine in all my other DAWs, so I do not know what is happening there. Any suggestions?
Windows DAWs it works fine in (all most recent versions):
Samplitude Pro X3 (my main mixing and editing DAW)
Harrison Mixbus - original and 32C versions (playing around with those)
Cakewalk Sonar Platinum - mostly for Melodyne and audio-to-MIDI. That may enjoy more use someday.
DP is primarily my composing DAW - I love its templates and chunks approach. Still new to it, though.
I have re-examined the PSP Master Q2 plugin but it continually fails. PSP PianoVerb loaded fine.
Any suggestions would be welcomed!
