Final Fantasy Fables Chocobo Tales - not working anymore

Hi, I was wondering if someone could help me with this. As I listed the game is not working anymore. I'm using M3 Real to play the game and it was working in the afternoon, just today, and now its not working. the M3/G6 comes up and says loading then when the title screen should appear theres a blank screen. I've tried removing the game and adding another file in. I think I might have to try to delete my save. Anything else I could do? Thanks!Also while I'm asking for help. How do I change the font style for the M3 list of games and such?Thanks again!

Yeah try deleting your save if youve used cheats at all, otherwise im not entirely sure why it shouldnt work :S
