Assuming that you are speaking of the MK program,
So first you need to "import" and "back-up" your "game data" from your PS2 to your PC by using the Sharkport. Assuming that you have done this already, you now need to open the MK program and then click on "file." Then click on "read garage."
At this point you will be prompted to chose the file in which you saved the GT3 Game Data.
The Game Data usually resides in:
C: Drive ---> Program Files ---> Interact ---> Sharkport ---> Savedgames. Then select your Game Data Save and it should then show up in the program.
