Seems like a strange issue.... I will ask a few questions then see can I help with this.
Was the game purchased through Origin?
Can you see the registration code in Show Game Details in Origjn?
When is the registration code requested?
Well i can show you that i have bought game on origin and activated on it.http://www.part.lt/perziura/3228ef1c3c3693cefca469bb162464b8141.jpg and on my origin account.http://www.part.lt/perziura/248f2352b2e495c14124f919b3ba5d0372.png and when i updated game and launched it i have to input Registration code. But i have no idea where to get it.... I bought that game from here http://buypcgame.eu/en/257-the-sims-3.html
