a few weeks ago my new win 7 computer arrived. and i installed fsx gold. it ran great for 3 days, and then the computer went kablooey, and i sent it back.  well my new, new computer arrives tomorrow. it's windows 8.1 64 bit.  i feel like i should be able to use the fsx i just bought and was barely able to use.  should i expect registration problems? if so, what are my options?

i am surprised, i would have thought by now someone might offer an answer.
