I have tried for about two hours now to get the save files Iīve found from internet to work with my wii but without success

When I try with SaveGame Manager GX it says "Unable to SetUID" and I have also tried with Savegame Manager r79 by Waninkoko with no luck.
Also tried to just copy the files from Data Management from SD card to wii, says "The data may not have been moved/copied".

I have a softmodded wii 4.3E with Priiloader and "Remove NoCopy Save File Protection" enabled. What more to do??

I have placed the data.bin file in usb:/private/wii/title/RMCP.

Please anyone who can enlighten me?
