The only time I ever got "cannot move to library" with 1.7 was when I'd deliberately changed the name of a file while it was still incomplete (necessary to avoid overwriting of multiple files from Windows hosts who use grossly long file names instead of folders to organize their collections)

Now I've upped to 2.1.3, it seems to happen with specific hosts - usually ones that have lots and lots of what I want. I'd think it was just another even wonkier variation on "cannot download", except these hosts usually show 4 stars.

I'd like an answer too.
