Snapshot cannot recognize that I have a backup file, even

Snapshot cannot recognize that I have a backup file, even though I've done the scan and placed the zip file into the right directory.

The scan says "Processing archive: 51b89fa1e38f17724_20130612_datenightplansnow_package.zip" yet it never appears as an available snapshot.

I am just trying to restore a site after something got really messed up.

Please help.
