So project should have been done today but then started getting this. I mean, even after googling it its is meaningless so know idea what to do, how to get my project back and ask my boss to be nice to me lol!
Can you help ????
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.
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.
