Can you quote the error message in its entirety, word-for-word, verbatim?
Did you get a new camera?
That could be it. Canon T3, I did upgrade over Christmas from the Canon EOS rebel. The message just said Unknown errors occurred. I can tried to import again and see if I get another message or more info
The error message probably said "unsupported or damaged"
The T3 requires Lightroom 3.4.1 or later. You can either upgrade to a more current version of Lightroom (version 5.6 is the most recent) or you can use the free Adobe DNG Converter to convert the RAWs to DNG, which should import into Lightroom properly.
great, thank you! I was wondering if I should use the DNG. I was going to try that if I couldn't get anything else to work! yes, I need to upgrade!
