What's the problem? Describe what went wrong.

If you import a .bin savefile of a specific game and the \data folder of that games savefile(the one that opens with "Open Wii save folder") doesn't exist, the import will fail and you'll get an error message "Failed to import save files".
It will import properly as long as the folder exists, even if it's empty.

The issue wasn't present in 5.0-7964 so probably not.
