Cant load game

Im a sims player on xbox and ive had nothing but issues since the marketplace arrived. Now, i had hopes after the update however it now seems that i cant even get my game to open. I am fed up, absolutely and completely sick to the back teeth, the money i have spent on this game is no joke. I am ready to delete my entire game and never play again. Why are you adding all this new stuff when a lot of us cannot even load our games. I want my money back, every penny because im absolutely disgusted by this. The whole thing is an entire sh*t show. Im sick of it. When are you actually going to fix the problems?
