As I stated in the other thread, you should definately re-register. I don't know Tom's personal take on this, but I'm pretty sure he would agree. Perhaps one could work out a deal for a seperate license for another PC. I have a laptop as well, and I use that to test and set up new features before they make it over to the arcade PC. As stated previously, I had anticipated this would be the case and I donated an extra $15 when I acquired the license to help recoup some of the cost. Again, you'd probably want to email Tom and ask him personally.
