What's the disadvantage of not including your option01 file? In other words, what difference does it make keeping one's own in conjunction with all the other files?Go into your documents folder - USERS/[You]/documents/Konami - in there you'll see a save folder, replace that folder with the save folder you've downloaded. If you want to keep achievements copy your own option01 file(found in your old save folder) into the new one.
Game saves can also be copied across too - just copy the ML01(master league), BL01(legend), CL(cup) files into the new save folder from the old.
Cheers
