When I try to open my site I get "NOF has detected an unstable file" error. Clicking OK causes the program to quit. I tried this several time and each time a new file is generated in the "Recover" directory, each with the date and size of the last time we published.
1. What causes this error and why doesn't it recover
2. Can I use one of the recent recovery files to get around this? If so, what is the procedure to do this?
