Error 2.1.1x7 (cus we all know what that means right lol)

As Alan notes, if you send me a zip file (usually via a download link from Dropbox or a similar service in a forum private message) of the project (or at least the Ch Data/repo.noindex folder), I may be able to fix this.

If urgent i tend to invoke the magical dtull-adobe​ incantation. He often asks for a zip of the project to be uploaded. The error indicates a corrupt project, which sometimes he can repair.

Try creating a new project and importing your previous one into it.

When do you get this error, only while clicking certain things? It comes up immediately after you open the project? Something else? Please provide as much detail as possible.
