Not sure if it will work with this, but I used to use scriptvessel in two computers by running it in a VMWare Virtual Machine and blocking it via the firewall. When i exited it I didn't shutdown, and when restarted I could simply resume. I had a version of Scriptvessel on that virtual machine for a couple of months or more which continued to work for the next pacthes after my subscription had expired. This would also mean you would be able to log in on another computer while the subscription was valid. Or if you had a computer that did not turn off just block it via the firewall and log it in on another computer. I think this would be your easiest way to do it apart from learning a bit of Assembly and cracking it yourself comparing the before and after of the login. Just my 2c.
