It works for me. Make sure that you put everything exactly as it says. Double click the message they want to select all of it and paste that directly into the empty message box. Make sure you have no extra spaces. When you copy the signature, double click the box to make sure that you have selected all of it and when you paste it into the signature box, make sure there are no extra spaces.

No. It just means you cannot change the text. Just double click it and copy all of it.
