i have downloaded alby's patch however i can't find a STEAM/steamapps folder.. even though, i was able to save the contents of the player folder in the nba 2k9 folder in drive C.. i also saved the contents of the rosters and slider folder in the SAVES folder.. however, i can't find these files in the LOAD/SAVE option in the game.. overall, nothing changed. no rookies, no new player.. and also how do you use texmod? it does'nt seem to work.. mine always says SHIT HAPPENS.. please help.. thanks..
