Purchased Catch Box Pro, Zip File Not Downloaded

I just purchased Catch Box Pro. I clicked on the Download button in the receipt and it didn't download a ZIP file, it downloaded all the CSS and PHP files into a catch-box-pro folder in my Mac's Download folder. My Mac may have automatically unzipped the ZIP file as it downloaded it. Can your provide a direct link to the Catch Box Pro Zip file? Is there a way to prevent my Mac from unzipping the file during download?
