It's not listed in my games on origin either, but I know I registered it because it wouldn't let me do it again when I tried, I figured it either didn't go through or it needed some time to show up :/

I have been having a lot of trouble with downloading from the exchange, Telling me it needs updates i do not have. I noticed that fast lanes is not showing as installed in my launcher, though i have in game items, my game is registered. The only thing ones i do not have is the Katy pery one and the new stuff pack which i am still waiting for from a pre order of the 70 80s and 90s
