So early this morning I decided to download a plane from SP and it asked me where I wanted my files stored. Not thinking it through I clicked on "This Machine." Tonight I went to load a project I've been working on for some time and it loaded the version from about a month ago. Slight panic. Is it gone or is there a way to retrieve the version from yesterday? If it's gone I'll move on but I was almost done!

Thank you in advance for any help.
