Again, it's not showing any files. I'm using Windows 7. This may take a phone call to CC to straighten out.
If you cannot find the .vnu file, there is no way to reconstruct that. You will have to create your website over from scratch. If you have the HTML files still, you can use our HTML Editor to make your modifications instead. Just note that the HTML Editor is not a visual based editor and you will have to code your website.
What I suggest is if you start over with VSD, start making good backups. Using Dropbox is a perfect option. It is free and automatic.
