I thought I would try the Mini-Bridge on my os X, running 10.6.5, with Symantec 10.2.3. Reading up on this error, I have removed the Switchboard Pref folder and restarted.
To its credit, it did attempt to see in my home folder when I clicked Favorites, but nothing in my favorites, though. Trying another folder, brought up the message again and I cannot even get back to where I saw my home folder. Unsure of what other troubleshooting I can do. The knowledgebase articlet focused on PC's firewall settings, which shouldn't apply here, sam
On PC, the way to fix this is to remove the csxs2.pref file from the \Application Data\Adobe\CS5ServiceManager\preference foilder in your user profile, then restart and close bridge. I suspect there is something similar in your user library on Mac.
You might need to restore Bridge CS5's preferences. If necessary, quit out of Bridge. Relaunch and quickly hold down Command+Shift+Option (Mac) until you get a dialog. Then choose to restore preferences.
Thank you for this response. This one worked promptly and I'll be glad to tell my team, sam
