I'm running photoshop CS5 (Old I know) on my Mac and I've never had trouble with it. However, I just made a flyer and "Could not complete your request because of a program error" came up when I try to save as PDF. I've restarted the program and my computer and it keeps happening. I even created a new file and saved it as a PDF and that worked. It just seems to be this specific file. I've searched forums about this and tried all of the answers and nothings worked. I'm starting to get frustrated!!
