Hi Jencie
We first need to determine if it's just this single
application or if RoboHelp itself is wonky. Are you able to open
RoboHelp HTML generically? Create a totally new project or open one
of the sample projects with no issue? If you can't do that, you are
possibly looking at reinstalling RoboHelp. If the other projects
open without issue, you are facing an issue with just this project.
If this is the case, the answer might be as simple as locating and
squashing the ProjectName.CPD file, then opening the project using
the .XPJ file so the .CPD will be rebuilt.
Hopefully this helps... Rick
