I, too, found the same error when I tried to view the example file. So, I gave up on it. Instead, I'm using a different example file (graciously supplied by a member of our community) and the help I get her (particularly by Paul). There are several insights I've discovered by trial and error because the specific sequence is not laid out in the manual. For example, placing a list of eight items in two columns on a slide worked only when the two colums (under the overall heading of "columns-top-aligned") and grouped and indented by one level. This community here is a tremendous resource and always willing to help. Try creating the presentation you want (ignoring the example file) and ask when you get stuck. Rich -- Dr. Richard B.
