AI file looks and exports as if it's blank - but it isn't

I have been working on this file for a few weeks, and just finished the project. I went to package the file to send to the client, and when I open it, it looks blank except for one small section which shows. When I click on the objects and open them in isolation mode, they show, but when I de-select them, they disappear again. Toggling eyeball icons in layers does nothing. I can work with the file if I select the objects before I work with them but it was a big pain. I tried re-linking some things, that didn't fix it. I tried exporting to PDF and it came out blank too. The layers look populated. I restarted my computer, that didn't help. I haven't uninstalled and reinstalled Ai but I may do that next unless someone has an idea what could be going on. It's just this file, I was working with another file at the same time and it was fine. I am attaching the PDF (couldn't attach the AI file?) because I'm at a loss right now.
