I'm using LR 4.4 but it hasn't worked correctly since I got my new camera (Canon 70D). When trying to import I keep getting the "Preview not available for this file" error message. I had some better luck connecting the camera with a usb cable, that let me see the jpg images, but it would not let me see the raw (.cr2) images. Would I solve this problem by upgrading to LR5?
I'm running LR 4.4 on a Windows 7 PC.
Thanks for any help that can be provided.
