I am trying to restore bookmarks to Version 5 from a backup I made from Version 4.+. I get an error message "Unable to process backup file." What's wrong?

I made a backup of my bookmarks when I was running Firefox Version 4+ (stored in a "json" file on a thumb drive). My primary hard disk crashed and when I down loaded Firefox on to a new hard drive, I got version 5.0. When I tried to restore the saved bookmarks, I got an error message that says "Unable to process backup file."

A possible cause is a problem with the file places.sqlite that stores the bookmarks and the history.

Thank you so much for you reply. I just got back in to town and have not had a chance to try the suggested solutions. Now, at least, I have someplace to start. Thank you again.
