Final Fantasy X save game problem?

[linton]

Hi, I think I might be having a problem with my save game file on the memory card.
I havn't played it for about a month now, and my sister wanted to start playing it the other week, so she started her own game.

It was fine up until the every first fight, the point where the pod things fly off of sin, while tidus and the other guy (its really showing that I havn't played it in ages) are running on the bridge.

At this point the both walk to the same point and it freezes. Well, It dosn't actually freeze, the music plays fine, and both caractors go about their normal movements that they do while left alone, but they won't move, monsters don't come, nothing.

Sooo..... after all that, my question is if anyone else has had this problem, and if they knew if the problem was the save game or not.
Unfortunatly, I don't have two memory cards, and I don't really need two, so I don't want to have to go and buy another one just so my sister can play FFX.

Oh, and deleting my save game isn't an option.

The best way to solve it is to tell your sister to buy her own PS2, her own FFX and her own Memory Card..

I never had this problem if I am thinking of the correct spot in the game
