You probably understood this already, but I first went to x-aviation.com, my account, and realized I didn't actually need to do anything there. So I then reinstalled all three products into XP11 and this time, thank you, it all worked. Including SoundMaxx. Great to be back in business! I did a flight yesterday in 11 and remarked that the weather depiction was so garish and artificial I would probably not use that version. Now that I have SMP restored I can proceed knowing the weather will look terrific again. Thank you very much!!
