I am not with Laminar Research; just a flight simmer.
Like you I have a disc version of xp10. I invested in a USB dongle that acts as a substitute for disc 1 . Details can be found at https://www.x-plane.com/product/x-plane-10-home-use-usb-key/
Alternatively contact Laminar Research at email@example.com to arrange a replacement disc.
