In early November 2018, it was announced by Swiftpage that the embedded third-party software component of Act! that facilitates the licensing services is being discontinued by the manufacturer at the end of 2018. After January 1, 2019., certain common actions you may take that interact with the licensing component will cause Act! to fail and you will no longer be able to access your database. Examples of these common actions include attempting to install Act! on new hardware, modifying existing hardware, and modifying your user count. 

Swiftpage have a solution however it will require an update to your Act! installation prior to 31st December 2018 to avoid any interuption to your service. For more information and how to update Act! see Changes to Act! Software Licencing
