Could you please copy the images from the SD Card to a Folder on the computer and then import the images in Lightroom from the Folder that you have saved the images to.
Please let me know if that helps.
You don't have write permissions to the destination folder.
Yes, I finally figured out this was the problem. I am not sure what happened to my external drive as it was formatted for the Mac and I've been using it for a year. However I just upgraded to El Capitan and Office 2016 and somehow this drive got reformatted to the windows system. Thanks so much for your help - now on to the figuring out how to reformat the drive!!!
