Toon Boom Studio from one computer to another

Is it possible to go on another computer in my home and put toon boom studio 5.0 on there for free? Or would it cost me another $320? Or would I have to pay extra for the upgrade to version 6?
Thank you to anyone who helps

You can install it on a maximum of 2 computers. If every you wanted to move it to another computer, you would need to return the license on one of the previous computers.

Also if you upgrade to version 6.0, you will need to return the license on one of the computers and then enter the upgrade code on the other.
