Ok, honestly the trophies are pretty straight forward (do this and boom), but for the one "Earn a platinum medal in any race". I earned a platinum trophy in the race right outside the villain night club place. I am a free to play member, is that was is causing me to not earn the trophy?

I got that trophy with the first available race but I was playing the retail version at the time. You might want to check their sites forums since the people there are pretty die hard about the game.

I'm fairly certain with the game going F2P they changed the trophies in the game. I noticed earlier that I now have fewer trophies to get compared to when I first bought the game.

I just started on F2P and didn't get that trophy. Threw them a few bucks to go to Premium, still no trophy. Bummer.

You can only unlock trophies with the Legendary membership (monthly payment), it kinda sucks. I learned this after getting my second character to 30 and not unlocking the two trophies I should have gotten.
