What exact error message are you getting when you try to import the DNGs created from your Canon raw files?
Also, what version of the DNG converter are you using?
I have a friend who told me I have to run my files through the dng (adobe) converter and I didn’t know how to do it - but now I do! Thanks for your response.
helpful - appreciate the prompt feedback!
