how do i play story mode twice? i played it and completed it once, and now, when i try, it just starts like the endless mode, with building a robot, or start where i left off. i tried restarting (of course) but i ALSO tried to DELETE the folder, and unpack it, AGAIN, and THEN try to play the game, but it STILL didn't reset! which is really weird, and that was a NEW folder/file, as i deleted the first one. do i have to get a new game folder (the one you unpack to get the folder with the game in) and if so, do i ahve to pay AGAIN? REALLY confused, as i don't understand how it can remember (so to speak) what i did in the game, when i delete the game file i used, and unpack a NEW one. >.<???????
