HI,
This happened to me when I did a little reorganizing of my desktop files. I came to this thread looking for help as well and none of the previous suggestions worked. So I decided to just try something and see what happened. As soon as I moved the Quickbooks file back to it's previous location the problem went away. Maybe the same thing happened to you, or more realistically other people reading this thread who are having this problem because more than likely you resolved this months ago. ;)
Hope this helps someone!
Reese
