Hi @gregmwashington, thanks for your message. Are you still having this issue? Because when I looked at your site, the Mercury Display font is showing for me:
You might also check what browser you are using to display this page, if you are using some browser like Firefox or Safari or IE, you might have to upload the other font versions that we recommend you upload, for compatibility sake, which is also the woff, eof and ttf versions of the font, if you have not already done so. You can get those extra versions by converting your font at fontsquirrel.com, they have a free utility on that site you can generate your webfonts needed based on a font you upload to that site.
I hope that helps, let us know if you have any further issue. Cheers, Dave
