Maybe you don't have the folders properly named: "private/wii/title/xxxx/data.bin" where xxxx would be the four digit game code. Another thing that might be causing a problem is that the saves you've recently been downloading are from the wrong region. Besides that, the only other thing I can think of is that the saves are in the wrong format. There's ".bin" which is the default format and ".wii" which is for the Datel Power Save product. It's supposed to be stated somewhere in the save's description if the file is in .wii format.
