It is possible for certain changes to cause your computer to be seen by iLok servers as a new computer.
When licenses are activated to a system, they are stored on that computer. There is no way to deactivate licenses without access to this computer.
If you are unable to access this machine, we can manually reset the locked/lost activations for UVI licenses.
Please Contact Us and provide us with your iLok User ID and the Location ID of your computer, which can be found on the Show Details page in iLok License Manager. We will then manually reset the activation from this machine.
