I have purchased Xplane11 by Laminar Research as a set of 8 DVD's from "aerosoft" I run it on Win10 with a Thrustmaster stick. The simulator ran for about 2 weeks but now each time I start it up it requires me to place DVD #1 into my computer to unlock the game. The computer is always connected to the internet. What can I do to overcome this requirement I do have all registration keys/ etc.
TIA
Kind regards,
Russell
