Could you please confirm the version of Lightroom that you are using,
Also please copy the images from the Card once to the Desktop and then try to import the images in Lightroom and see if it works.

The most common problem for "cannot be read" is a WRITE permissions problem on your destination folder. (This is a common problem with mac OS upgrades.) Using Finder, make sure you have READ and WRITE access to the whole directory tree you are trying to put the images into.
Please select another Folder in the Destination Panel , and see if you are able to import the images.
As it could be a permission issue.
