This is in Windows 7 x64. No matter what folder I select it shows up like the above screen shot. In the folders there's CR2 files from my 7Dii, jpg's from my phone, other jpgs, movies, etc. But it shows every single folder as being empty. Any ideas? I don't recall making any changes at any point in the last few days to settings. No idea what happened.
edit: previously imported images show up in the catalog fine.
