I work on a PC - Windows Vista, and currently use Lightroom 4. When I try to choose the 'edit in' option and go to PSE11, it will go there and open the file, but it won't let me do anything with it. All the buttons/masks...etc are faded out and when I scroll over them a circle with a line through it comes up. Is there any way to fix this so that when I edit-in from Lightroom to PSE11 that I can actually use it? And if not, how should I save my files then so I can re-open them in PSE11? Would they need to be JPEGs, or something else? I shoot in RAW.
