I downloaded Marvel Vs. Capcom: Clash of Super Heroes (USA 980123) (mvscu) 864kb and I try to load and get this error:

But I get this one: Marvel Vs. Capcom: Clash of Super Heroes (Euro 980123) (mvsc) and its at 22mb and works fine
Why is it that i am not able to use the previous file?
I have this problem with other games also
