Need to uninstall the Vertigo license, but are unable to.
The Vertigo license is located at the root of the primary GroupWise domain directory. For example \\Server\vol1\grpwise\domain. It will be a file called vertigo.pem (by default). Delete the vertigo.pem file and the license will revert back to demo mode. This limits the capabilities of Vertigo and the time frame that you can use it.
