I just installed Photoshop CS5 and am currently running iphoto 09. iphoto has all my photos but I want to open just one photo to edit in photoshop. I have tried several things: clicking the iphoto file and dragging it into the photoshop icon on the dock, saving my iphoto file as a JPEG and other photo files to see if that makes a difference, opening a photo from photoshop bridge, etc. Every time I try to click open file in photoshop and choose a photo file it gives me the same error message: "Could not complete your request because of a program error." I'm confused as to what program error? Please help.
