Using photoshop elements 11. I several files, (at least 4) which I had been working on for several days, saving regularly. I put the project down for about 2 weeks but tried to pick it back up today. The files are gone! A search for the files brings up shortcuts to the files but the shortcuts don't work because the files are gone. These are something I put a lot of work into, I would not have deleted them accidentally.
Virus scan shows no viruses.
Also, some of the files that I was working on at the same time, part of the same project, are still there! I am so frustrated and confused!
