I have a slight problem with that the font I’ve added is being overridden by the themes settings. I change the options.css from font-family: Open Sans !important; to font-family: Thirsty Script !important; and it changes for a while but then reverts back to Open Sans.
As you theme is already using !important (means force the font to be used). So our plugin is unable to over take it. However, there are some other css trick that can be done.
Before i can suggest you that, can you please send me your site url ? And snapshot of the section you are having issue with.
