I lost my XPJ file. I had a co-working provide me with the same XPJ file (I had a copy of her files), but it is not detecting all of the files (index, glossary not working, etc). I tried to copy all of the files to a new project but that doesn't work either. My project is already online and I need to make updates to it. What can I do? I am using v22.214.171.124
See Opening Projects on my site. There is a section on recovering what is missing. Not 100% sure it will work here as you have attempted to repair the project in a different way but I think you should be able to adapt the instructions.
See www.grainge.org for RoboHelp and Authoring tips
You may end up having to use the help output as your starting point and reverse engineer the project – see Peter’s site about that.
