For those of you who may still be having problems, I'm using Firefox if it matters, but if I doubleclick to highlight and then copy the import string, it generates a cell error.

But when I manually highlight the text out of pastebin from the end of the string to the beginning, and then copy that, the import works.

Not sure what encoding / copy/past shenanigans are happening here, but figured I'd post if it helps anyone else.
