accidentally skipped downloading font

When updating a project I hadn't worked on for a while to 10.3 I happened to accidentally click exactly where the 'skip' button appeared when it offered to download a font. I can't remember what font it was and didn't have time to read the whole message, I just recognised it from previously updated projects where this came up. It's totally messed up my titles. Is there a way to reinitiate this option or to fix it some how without manually changing all the titled to something new?
