I have been using Lightroom cc for three months without issues. Yesterday I tried to import photos from my flash card and received the following message: "the following files were not imported because they could not be read." I formatted the card, took more shots, and tried again to no avail. they are importing to Photos (aka iPhoto) just fine. Tried same with my SD card and no luck. Same message. I just installed the latest Lightroom update (2015.5) and still no luck. Please help.
