Bridge 11 Losing All Thumbnails

[Ocean 11]

It just started that Bridge 11 can no longer create previews of images.

Not only that, it loses all the thumbnails it had. I open a folder of images and they are there and then they go out one by one and I only have the Photoshop symbol.

Those are all TIFF files, layered or not, as soon as I open a folder, all the previews die and are replaced by the PHotoshop symbol.

What is going on here? How can I fix this? 

"Purge Cache for folder" does not work. Bridge has lost the ability to create previews of TIFF files.

I closed bridge and opened it up again a few times and then the thumbnails came back.

Lol! No offense - but how is this the correct answer? I get that it may have worked - but that's certainly not how this software is supposed to work. For me - I've resorted to having a shortcut to Bridge's cache file on my desktop. I often have to close Bridge - delete the cache - then reopen Bridge - all to get my thumbnails back. This is also a "correct" answer - but come on Adobe -  pretty sure neither of these things should have to be done. I used AcdSee for years, and never had the kind of problems I'm having wtih Bridge. Surely you have a bigger budget for development than AcdSee??

Sorry - not criticizing the responder. But it kills me that these work arounds are what we have to resort to...
