savegame installer problem

hi
i wanna get a save game for pokemon , i have tried a couple of them but none work for me cuz they have protection. the last one i tried was this
Wii Save - Nintendo Wii Game Saves > USA (Not.Bin) - 100%

using the save game installer but i get this error

Reading game disc... Error! (ret = -1)

what can i do to install the save game?
i tried tried first with a data.bin file using the sd card going to data management , save data , wii, sd card

i see the saved game but is a blank icon with ? (???)
when i try to copy it to the wii system memory i get

data may not be saved ...etc

is there any other way to install the saved game or how can i fix it ?
i also wanna know if is possible to load the game from the USB drive using gfx loader instead of inserting the DVD.

thanks in advance
