lightroom 6 cant find photos for import

I use lightroom a couple times a week & have never had a problem until today. I took over 1000 photos at a volleyball event last night. Trying to import them today & LR keeps saying no photos found. I can see them in camera. I was able to download them to my computer, but when I try to import then into lightroom it says no photos found. I have tried multiple card readers, tried connecting camera directly & importing from camera & tried downloading to folder on computer & importing from there. Nothing works LR continues to say no photos found. I am supposed to shoot another event tomorrow so I really want to figure this out.
