VirtServer Headless Deactivation

Hi folks

I'm trying to run a command that will silently deactivate my virtserver licence

i can step through using the license manager with

-jar /opt/VirtServer-2.0.2/ready-api-license-manager-1.1.jar -x

then following the menu options however I want to do this without user interaction

has anyone else done this??

thanks

Mike
