Silver Efex Pro 3 will not load any image. It hangs while loading. Photoshop and Lightroom give me the same result when I select Nik Tools/Silver Efex Pro 3. I have the latest updates to all the affected software. I tried uninstalling and re-installing with same results. I also uninstalled the latest version of Nik Tools 4 and re-installed an older version of Nik Tools 4 which also did not work.
