It sounds like you're using the now legacy version of Divshot. We recently launched Divshot 1.0 with file support and a completely revamped project structure.
Legacy: http://app.divshot.com
New Divshot: http://builder.divshot.com
It's on a separate instance so beta users have time to export their pages and finish anything up in the old version before upgrading. Since we moved from generic folders and pages to actual files we're offering a manual upgrade.
If you'd like to update you can just go to https://api.divshot.com/upgrade and follow the instructions there. We're pushing a notice to the old version right away to eliminate any confusion. Sorry about that!
