I am getting back to RCV3 after a long hiatus and I am now running Windows 2000 Professional. I used the key that was sent to me, but I am not sure if it took.The load flight plan button is grayed out along with most of the other buttons.I don't know what could be causing this behavior.thanks in advance,Tony in Miami

If you have reformatted or replaced your hard drive or reinstalled your operating system you will need a new key. Send your request to [email protected] with a subject of RCv3 Key Request.
