I agree with @DoninGA on this....the only recourse you may have at this point is to continue to try to work with either Windows Support or TTX Customer Support, or both and see if they can sort it out somehow...even if it take hours/days.
If you have a SDD on the new computer, In past years, there have been unusual problems with installing on new computers with brand new SDD drivers that TTX developers hadn't encountered yet. But that's just wild guessing side-note that may have nothing to do with your problem.
