Just to confirm, does the error appear if you run Templates on another machine while logged in to the same account as on the affected machine?
Please send the Formativ configuration from the affected machine to email@example.com. You can obtain the configuration by selecting Help | About Formativ… from the GroupWise main menu. When the About Formativ dialog appears, go to the Configuration tab and click the button Copy to clipboard. Then paste the text into your reply email (or save it to a plain-text file and include it as an attachment).
