I suggest you try entering the registration code manually, ie. do not ‘copy and paste’ the code.
If the above does not help, please send the Formativ configuration 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).
