I am getting a message that my files could not be read after I have plugged my card reader to my laptop and tried to import my picture files. I tried uninstalling and reinstalling Lightroom 3 but it still gives me the same message. Any suggestions?
What version of Lightroom are you running, and what's the camera type that you're trying to import pictures from?
Have you attempted to copy the files using Explorer/Finder directly to a hard drive and then importing from the hard drive? Doing this would give you/us an idea of where the problem might lie, e.g. faulty card, card reader, cable, Lightroom.
This sounds like the same problem that my husband had today. He spend hours trying to figure out what was causing it.
Turned out it wasn't that Lightroom couldn't READ the files, it was that it couldn't WRITE them, because the target hard drive was full.
That's a pretty useless error message!
So check your target drive isn't full or hasn't got write permission restrictions.
