Unable to copy datas - Savegame manager GX
So I used a NAND extractor to get the saves and Mii's from the NAND and I've successfully got the Mii's on my Wii, only problem is trying to get the saves to extract and install is a nightmare, I have Priiloader and the hack that removes the copy protection and I know about making the saves on the actual games and then going into the savegame manager. But when I go to actually install the save onto the Wii it just says 'unable to copy datas' I've got MH3 to work but every other game just throws back that sentence. Any help?
P.S. I've tried other Save game managers and the save either won't appear or it will just install the one I made before
