This occurs when Vertigo is not able to detect a license, and the 30 day trial has been used up. The 30 day trial goes with the calendar
month, meaning, if you download the product on the last day of the month, and don't install it until the next day (the first day of the next month) your build will be expired.
In order to resolve this issue, you will need to either License the product with your GWAVA sales person or contact your sales person for a new build.
If you already have a license, and it is installed in the GroupWise domain directory, make certain that it has been renamed to vertigo.pem or it will not be detected by Vertigo.
