I've just upgraded from a Macbook Air to Macbook Pro and have migrated my catalogue over to the Macbook Pro. When I open LR (I have Creative Cloud) I can access and edit my photos but can't import any new photos into the catalogue. I've reinstalled LR 5.7 and tried again. Am trying to import RAW files (CR2 and ARW, neither will import), and I get a message saying it can't read the files.
Any ideas what to do?
