We answer questions that are emailed to us about difficulties in running Topicscape. You can reach us through the Contact Us link on every web page, and every page (except the wiki) also has a small "Question about this page" form at its foot. When reporting a problem, please always send a log if possible - it will allow us to resolve your issue more quickly. To do that, start 3D Topicscape and, in the "Help" menu, select "Send error report. . .". If you cannot start 3D Topicscape, please try uninstalling it and then re-installing.
