Can't upload media or metadata

[Former user]

My Windows 10 device can't download any metadata or media. It occurs when i'm done trying to upload metadata or media. To reproduce the issue, I had to go through a wizard to download Metadata and Media (I used the Wii version of Smackdown Vs Raw 2011.) When i'm done, i click finish, and look what i get:

The given key was not present in the dictionary.
