Hi Kay, 

Welcome to the Box Community, I'm happy to help!

If you no longer have access to a shared link of a file, we recommend reaching out to the person who shared you the link and request access to the file again. If your Shared link access has expired, they may set up a new link for you to access.

To learn more about using Shared links, please take a look at this article: Creating Shared Links

Thanks for reaching out and let us know how else we can help!

Regards,
