If Pro Tools crashes when trying to create a new session or open an existing session, the DigiBase Database may be corrupted.To determine whether or not the DigiBase Database is corrupted, launch Pro Tools, open the Workspace browser, and revealthe contents of each drive one at a time. If revealing the contents of a particular volume crashes Pro Tools, its database fileis probably corrupt. To correct the problem, locate the Digidesign Databases folder on the specific volume and remove or renamethe volume.ddb file (for example old volume.ddb). Restart your computer and launch Pro Tools to create a new volume.ddb file in the Digidesign Databases folder. If the crash does not recur, the old volume.ddb file is corrupt and should bedeleted. If this does not correct the problem, please contact Digidesign Technical Support. It is recommended that you regularlyback up your system as a safe guard.
