When I try to pull up Trilogy as a plugin in ProTools, I get the message, “UVI engine error. Could not change preset. Error 1409.”

To fix this, trash ProTools preferences by following these steps:

1. Quit all applications.
2. Double click the main Mac HD and go to
Users > your user name (the house icon) > Library > Preferences.
Inside this Preferences folder, locate and trash the following items:

com.digidesign.protools.plist
DAE Prefs
DigiSetup.OSX
ProTools v6.x Preferences.

3. Empty the trash, launch ProTools and try Trilogy in a new session.
