PT crashes when starting session from Harddisk

Help! I'm working with OS X "Tiger" and PT 6.9.2 When I'm trying to open a session from my desktop, PT always crashes. When starting from my external harddisk, it doesn't... On my internal HD there is enough space (80GB) left... Checked the "Workspace"-Window too and it crashes, even when I set both harddrives to "R" (like Record)... I'm also unable to create a new session on my (internal) harddrive. On the external disk it is possible... Any idea? Thanks!

Repair permissions maybe? (see "General Troubleshooting" thread)

Hi, found the solution: Delete the Digidesign Databases folders on all mounted hard drives, then delete the "Volumes" folder in MacHD > Library > Application Support > Digidesign > Databases. Empty trash, then restart the computer. Works perfectly! philoton
