Forum:I just beat the game, but it wont allow me to play through a second time? Anyone know why?

I just got done beating the game on veteran. For some reason when I go to "resume" or try to load the last save as I did last time I beat the game on normal, instead of allowing me to play through the game again, it forces me back into the second part of the final fight against Saren. Anyone know of any reason why I cant play through the game again?
