Error While Trying To Protect File(s)

This message pops up when I click on a Windows Explorer file. Then when you click OK WE continues to do as expected. Other applications don't seem to behave as nicely as WE and just die at that point. I found a reference to it in the French forum but no English response.

Has anyone else seen this error and better yet resolved it?

I sometimes get a variation on this "Error while trying to start protect file(s)".

BD also just made it worse with an automatic update that left my system in a state that when I click on a file or folder in WE, the BD install wizard starts up.

Un-installing BD seems to resolve the second issue, but the original symptom still remains but with the second variation of the message.

Any thoughts would be appreciated.
