Hi,
I changed computers because my laptop died and now I have a mac mini and am having trouble with goprism reflector. I downloaded the "prism fixer" but it did not work. below is the text copied from that program as you suggest:
-- Indigo Folder/File Permission Fixer --
Home User: alexdiaz
ID User: root
Folder: /Library/Application Support/Perceptive Automation/Indigo 5
Repairing Indigo folder owner and permissions:
Original: drwxrwxr-x / alexdiaz : admin
New: drwxrwxr-x / alexdiaz : admin
Complete.
