You can try to delete the part you posted below (including the last !).

In case you can/want to send me your changeset (or the image and
changes file) I can take a look.

Just to make sure, you selected the top item in the list shown after
selecting Tools > "Recover lost changes..."?

Cheers,
Adrian
