1- Close Pyramix and go to C:\ProgramData\Merging Technologies\Plugins then…
2- Rename or delete the AvailablePlugins.pms file and delete any files that have a .crash extension.
3- Relaunch Pyramix.
Also, I reinstalled Pyramix, the Lexicon bundle, the latest iLok software -- no success. The Lex bundle works just fine on the same system in a different DAW (Sonar).
Any ideas?
