Why does my nba 2k12 take forever to load,1st time i noticed this is when i played Creating a legend mode and did, workouts and now takes forever to load , i even left it on loading mode for 2 hours , it doesnt lag , the screen keeps on moving?

Is this a Ps3 problem? or 2k12 itself , if so help me please
Im playing without internet connection,

Could be a ISP Problem. do you have high speed internet?
