Problem
 

I installed MVP baseball with the crack. But, when I try to start the game I get a black screen then just back to the desktop.

What happens when you run it without the crack?

It asks for cd2.

And then? When you insert your original CD2. What happen?

It says incorrect cd, please insert cd2.

When you really get this message when you use your original cds without any crack, you should bring back the game to the store where you bought it.
