I am trying to import photos from an SD card but it is showing blank. I know there are raw images on the card because I moved them to a folder on my computer thinking that there may have been a problem with my card reader. Now trying to import any photos from my computer into lightroom there is nothing showing, it is just blank. This is just a recent problem, because about a month ago I was importing just fine from both my files on my computer and from my SD card. There are no XMP. files in the folders. My computer has been prompting me to upgrade to windows 10 and I have not done it yet, could this be part of the problem?
