I did find AppData but my problem now is that there's no folder called 18.104.22.168. There's one named called 22.214.171.124...
Would renaming it solve my problem, and if so, does renaming it means that I just add, say, _?
Update: I tried to rename it but I still get the same error message.
126.96.36.199 is for Studio 2017.
As I said, it might well not solve the problem. Rename it back quickly before you lose anything.
My Music in Documents is most likely empty anyway. My Music on my computer is in the same folder as My Documents, and My Music in My Documents has nothing in it, and cannot be accessed.
What are you trying to do with that folder? It doesn't sound like a natural place for translation packages.
