Files\Digidesign\DAE\DAE Prefs.
2. Open the DAE Prefs folder and delete all of its contents.
Pro Tools Preferences:
1. Open My Computer\System Drive (C:)\Documents and
Settings\User*\Application Data**\Digidesign.

Volumes:

Files\Digidesign\Pro Tools\Databases.
2. Inside the Databases folder, delete the Volumes folder.
