Sorry about that --- the 111_legacy.zip was never zipped for clarity and just left there in the /legacy_upload folder. Just upload the full 1.20 files, and then that on top of it. You can just drag and drop the contents of that folder to your webroot, they will go to their indicated places. One file under /languages/en, two under /templates/pro/modules, and one under /modules/gallery. I have updated the documentation to indicate this.
