Use to work for me, now I get all the errors everyone else is talking about. Asks to create new folders, doesn't do anything, other than crashing frequently. Maybe an issue with Gmail catching onto Gdisk, or with Mac OS. Either way - product pretty well sucks now. Glad I didn't give any money, and I would have, but there's no support, not even documentation. Even some of the "about me" info is no longer good.
