Yeah, I had problems too. There was a game offer "Die Stämme - (engl. tribal wars)". The offer description said, who plays it and collects 85 points, gets more than 30 free tokens. I collected the points, even more than 100, but the tokens were not paid out. Really sad.

With videos I made good experience, except for the Sims-University video. It refuses to play (maybe it is a flash issue).
