HELP - Cannot use my flyers

Help, please! I have so many flyer projects for our school, that I have spent many hours working on for months. With the new update, almost every single flyer says it cannot be downloaded because it contains paid content. Some are easy fixes by just changing the font style and it works. For others, I have changed all font styles, etc. and it still says it has paid content that needs to be removed. How can I see what on the flyer is paid content or not so I can remove it? Why all of a sudden can I not download and use the flyers that worked just fine before? I'm so frustrated!
