Thanks for your feedback. I think what all of these plugins have in common (except PSP) is they are the latest versions of software that has since been revisioned or in the case of Altiverb, is about to be upgraded.
It is just strange, because there are no error messages from Ableton Live or Digital Performer or Final Cut Pro, etc., just Logic. So it seems the auvaltool is the problem, because again the plugins do work.
