Lost content/formating upfront

I just lost some of my content and can't restore it.

I had a page set up with tabs and links to download content. Somehow it just disappeared without me even messing with it. I tried restoring my page to a previous version but my changes that I saved within upfront aren't stored in the wordpress dashbord. Is there a way to restore a page to a previous version within upfront?

Thanks-
Eric
