Well, it seems that nobody in WD have time to solve this issue.
After lot of time I finally found a solution:
1.- Go to “C:\Program Files (x86)\Western Digital\Discovery\Current”
2.- Select “Properties” of “WD Discovery.exe”
3.- Go to “Security”
4.- Provide “Full Control” to “All Aplication Packages”
5.- Now you can login in WD Discovery again and you can access to MyCloud Home device as an external unit, as always.
