I had the same thing happen to me when I was working on a large project. I was able to find the temp file and rename it and got back a lot of what I had. It took me 2 tries, though. What is the easiest way to find the right temp file is to do a search for all files "modified" or "created" in the period of time the corruption happened. You have to delete the corrupt file and then rename the temp file "...obp". Good luck. Diane
