More likely you have the wrong folder selected.
This is how it looks. The path leads exactly to PlayerProfiles (global folder of all profiles), not to a specific profile. Any hints?
I would suggest trying the "Dev" tab and see if it can open your playerProfiles.lsb file (located directly under PlayerProfiles folder), and your meta.lsb file(s). The playerProfiles.lsb file in particular is more important here. If it can succesfully display this file, then I will have to ask you to send me a copy of 1. Your playerProfiles.lsb file, and 2. one of your save games.
Earlier it was reported that certain unicode characters appearing in profile names or savegame names can cause problems, so this could be the problem you are having.
