Replying to Computer help! hackers?

yeea so ive been living in the uk for the last few months at my moms house and i really dont have much to do, so i play internet games... cool i know.

anyway i love the game risk and i found this game

http://www.addictinggames.com/riskdl.html

u can download it there or from a differnt company but its the same game here

http://www.gamehouse.com/pc-game-download/risk?ref=gamedetail



anyway the whole point is it only lets u do 10 turns online and if you download it you just get a 60 min trial. basically what im asking is do you guys know how to crack the serial codes so i can play for free? ive looked on google tons and have found nothing..

sorry if this is dumb..
