Are you able to open the file at all or do you get this error message when you first try to open the file?
If you can at least get the file open, you can try exporting the data to a text file or using a clone to import the data from your damaged file. The corruption may still prevent this, but it's worth a try if you can get the file open.
No I can't even get the file to open.....error is immediate.
I'd love to be wrong about this, but I'm afraid you may be stuck without any other recourse except to revert to your most recent back up and trying to recreate the lost additions, deletions and edits.
ya....that's what I was afraid of.
