THE FIRMWARE UPDATE WORKED!!!!!!
I am very happy to report that after performing the firmware update fo 1.15 version, per online video posted on this forum, BOTH my 64 gb cards can be read by my K-r. Just to make sure, I reformatted them in the camera, so they should be ready for the big trip!
Thanks a lot to all who suggested this option!

Originally posted by Not a Number Sadly, the option with the SD MEMORY CARD FORMATTER did not work for my camera. I downloaded the formatter, suggested by Not a Number, but the camera did not read the cards.
However, as I reported previously, the firmware update to 1.15 version did the trick and both cards are now functional.
Thanks
