I have a Canon 5d MarkII use a Mac and have I used Lightroom 3 with this camera flawlessly until last month. Suddenly it stopped importing my CRW2 files. I have taken my card to another location and can import into lightroom 3 on a windows machine. I have disabled some security software, renamed catalogs and downloaded a new DNG file. I am at a loss. Should I simply reinstall lightroom?
Probably not. Are you getting an error message "The files could not be read"? If so, the real problem is that the files could not be moved/copied to the folder that you specified on import. Make sure you have permission to write to the folder(s) in question. Also, make sure you have free space on that drive.
Well Golly me. I did create a new catalog and yes it imported my files. I never checked the size of my old catalog before so maybe that was it. Thanks!
