I've suddenly been getting an error message in Photoshop saying that it can't open the file. And yet these files (jpg and psd) are files I've used for many months. Adobe support people checked the program and it seems to work fine to create new psds. Any thoughts? This would be devastating if I can't open these files - logo builds, graphic designs, etc. I work on PC - windows 2008 and am using Photoshop CC with the latest updates.
