I am using the Robohelp HTML demo. I have power point slides that I need to bring into Robohelp. I converted them to pdf but they didnt convert well. There were strange digits in some areas. So I converted them to .html files and then imported them. At first I exceeded the limit of files allowed to import into a demo so it stopped and only allowed those. I added an image map to one of the topics that linked to a pdf file. Now I want to see the result of how that will look and if it actually works. When I click on 'View Selected Item' a window opens and says the server cannot be found.

What am I doing wrong or what do I need to do differently? Any suggestions on getting my power point files in?
Thanks,
Fofe
