I have a new computer and want to move my catalog over. I first tried to back it up with Elements 13 but got an error message writing the file. So I thought I would get latest Elements 15 and see if the problem was fixed. I did that, upgraded, converted the catalog to 15 with no problem but am still getting the same message. "Error encountered while writing file(s). C:\ProgramData\Adobe\Catalogs\My Catalog 1\catalog.pse15db". How am I supposed to move the files if the mechanism to do so is failing?! HELP!
