Take a look at the file that you unzip. Originally I had everything missing when I pulled up my USB device on the PS3. So I went back and looked at the file folder. There were too many folders. Make sure its one PS3 folder, one Saveddata folder, then one roster folder. When I unzipped it, there was a PS3 folder inside the original PS3 folder, then the other folders. The extra folder seems to have been hiding the files.
