very true, the FADE being activated is my guess. I do know that this cd key reminder gets displayed every time i start toh with the acual key displayed for " cut and paste" but when i go to the tab "activate product" and use the cut/paste feature steam says the key is invalid. i have also tried to put the key in manually as well. as for Fade.. i t seems i can hold a nice hover at the very start of the game, however as time goes by it seems i get more wind/ sideslip/ GE bubble. after an hour or two trying to hover at ground level is like a ping pong bal in a vertical wind tunnel:)
