WebPlus X5: My Website has disappeared?

Hi, Can someone please help me? I have been creating a website on WebPlus X5. Today I went to open my saved website, however, it's not there? All my other websites are there but the one that I have been working on for awhile now isn't. I have no idea what has happened to it? I am extremely safe about constantly saving my work so that I do not lose it.

Does anyone know if WebPlus X5 has a backup of all the websites created, where I could possibly retrieve this?

I am extremely upset about losing all my work and have no idea where my website has gone.

Please help,

Thank you
