You are not providing any clear info about your system or what basic troubleshooting you have already tried. Start at “help us help you” up the top of each DUC web page. And provide the info asked for there... folks cannot guess if your profile info is up to date or which system this happens on.

What have you changed? When does this happen? Opening an existing session? A new session? Opening Pro Tools without a session? Have you even tried Trashing Prefs? Got removable drives attached? Try ejecting them all. Try testing from a new admin user account.

There are many many past threads on DUC about this error message. Use the site:duc.avid.com qualifier on Google search. And work through stuff there that has solved this for others.
