Can't Put Files Onto Game

[Everlyn]

I seem to be having an issue with putting files in the designated folder. On most of the downloads, the ReadMe gives the file location or two. When I try to drag and drop the file icons, from the file or desktop, it won't let me. I can't copy and paste any files there, either.

Tell me - am I just being an idiot, or is there a fix for this?

Thank 'ye much.
