I am considering buying a used copy of Real Flight 4 from a friend. Will I have any problems using it since he already registered it?
He will have to unregister it before you can register. He will need to send an email to do that. There is a thread about that somewhere in this forum. A search should find it.
edit........... OK, I did the search and brought the old thread forward so you wouldn't have to search for it. Your friend needs to unregister his copy before you can register it. There might now be that functionality on the RF forums by now. But if there isn't, the email should work.
