On 13th December I purchased the NCH Software Pixillion software in the folorn hope that I could convert RAW photo files to the JPG format. I did manage to convert some photos to the 'compressed' JPG format. All did seem to be good. Not So! Now, when I attempt to edit photos using my Corel PaintShop Pro X7 Ultimate, all I get is a message informing me that the file is invalid, unopenable and that I should verify the file. Just what that means, I have absolutely no idea. Does anyone have a step by step answer to this problem? It has arisen since converting with the Pixillion thing. Thank you.
