I ran 'Recover…' on the unzipped file and chose the 'Advanced' option, which found that the file has serious corruption issues. Lots of tables named 'Recover', and a 'Recovered Library' table. You may have to create a new file and build the schema from scratch to match each table - don't copy and paste, as that will just copy the damaged schema.
Hmm…The recovered file displays data, but the original shows "?". I ran the button script through debugger and saw it was sorting by the field named "Dat_e", then going to the first record.
Not sure what I was supposed to find, but you may want to run 'Recover…' on your file, then open the recovered file to export all of the data, as it does seem to appear in the recovered file, but not your original.
If your experience is different, I can attach the file I recovered to a future reply.
