Hi There. I just encountered the same message using Adobe CC and thought all was lost. I had placed a .png file within illustrator as a template to work from to create my lotus flower. After working on it for several hours and saving all along I closed the file. Later when I tried to open the file I received that same message. Then I realized that the .png file linked to my illustrator file was the one causing the problem. I deleted the linked file from the folder illustrator was referencing. When I tried to open the illustrator file again I got the dialog box that said missing links, replace or ignore. I chose replace and used a .psd file and voila, it opened, and all my work was fine. Hope that helps. If you're not sure which links are causing the problem, try opening each one in photoshop to see which one is giving you a problem. That's how I discovered the corrupted linked file.
