I have downloaded and installed the trial version of Adobe LiveCycle ES4 Designer. After creating a very simple XFA form, I cannot preview it in HTML. Clicking on Preview HTML tab does something funny with the UI and then just returns to the "Design View" tab. Manually trying to contact the localhost server e.g. localhost:8080/lc/content/xfaforms/profiles/default.html returns ERR_CONNECTION_REFUSED. Any ideas?
