Hello!

I have a sudden issue with my rhino license.

I have always used it between two computers:

PC 1  
PC 2

Yesterday I installed Rhino on a third computer ( **PC 3** ), logged off **PC 1** ; then I realized I **accidentally** assigned the license to **PC 3**. I logged off **PC 3** and uninstalled Rhino.

I came back to **PC 1** , and **I am unable to validate Rhino again** no matter what I try as the license became ‘stand-alone’.

I reinstalled Rhino on **PC 3** hoping to log back in and remove the license but I cannot log back in there either.

On **PC 1** , I get as far as entering the license key and when it asks to float between computers, I get prompted to log in, validate license, and then it fails.

It seems I’ll be chasing my tail for the rest of eternity.

**PC 2** still works normal, but I’m afraid I’ll get kicked out of there ventually?

What did I get myself into and how can I fix this?

Thank you for your support!

Maybe this training video on changing your licencing [Rhino - Changing Your Licensing Method](https://www.rhino3d.com/docs/guides/licensing/changing-your-license/) could help.
