Have been using Lightroom for years now and import Canon raw images no problems in the past. Just yesterday it now won't let me import. Doesn't give me any errors. When I go to import the .CR2 (Canon Raw file) they are just greyed out and won't let me select. I have tried to uninstall lightroom and reinstalled but still the same. I have downloaded Canon software and the laptop loaded the raw files no worries.
I have a Mac book pro laptop

Greyed out images cannot be imported because the photos have previously been imported into LR. Thus there is no need to import them again. You need to find the photos in Lightroom's Library Module and then you can use them in Lightroom.
