Upgrade from .hpj to .rhpj
I am trying to upgrade my classic RoboHelp project with .HPJ project file to RH2020. Had one through couple of help topics(links below) but everywhere it was mentioned to select main project file .XPJ to upgrade, which I am not finding in my project. I tried the same upgrade process by selecting .HPJ file, he upgrade was successful but when I open .rhpj file, CONTENTS and all other tabs are empty(Image below)
