I was having the same problem that the original poster was having ( Camera Raw editing is not enabled .) After tinkering around with some of the suggestions that were provided by some of the users on this form, I figured out what my problem was. How I got it to work was simple. I open a picture in Photoshop, doesn't what type, png, jpg, tiff. Then File>Browse in Bridge. Once Bridge is opened. All I had to do is, highlight the image you want to open in Camera Raw, and a second image, doesn't matter which one, then double click the image you want to open in camera raw, and voila, camera raw opens right up. After all the suggestions mentioned, this one works easier than the other recommendations made so far, every time. Hope this helps.
