CFs for rookies in 2011 roster Association Mode HELP

I found some wonderful CFs of 2011 rookies (with corresponding png numbers) and just added 'em in game(placed it in 2k11 folder)...
'
...But whenever I play Association Mode, those CFs doesn't show at all.

can anyone pls tell me why?...and what should I do to make 'em appear in game.

Any help would be greatly appreciated.

Thanks in advance!

anyone pls?

by 2011 rookies you mean players like cousins john wall etc. or do you mean upcoming rookies like derrick williams kyrie erving?

Did you overwrite existing files?

you have to go to the playyer and thne open up mp cyberface hack then put in the png in the 2nd box and click F2
