I actually can play, but my crack is bad and it corrupts my saves.

hatsukoii if you have MSN add me to your list I can send you my crack and you can tell me if it works with your Magna carta.

Make Sure the game version is 1.00 otherwise it doesnt work.

Oh I know what is wrong too : The crack needs a cd.

If you have alcohol 120% you can make a virtual drive and load the iso in there. Otherwise, Burn the CD and but it in ur CD drive.

It worked for me. please answer if it works for you to save and load a game. thank you
