TypeKit Web Fonts

It seems I can’t seem to get TypeKit’s web fonts to work with my theme. I’ve had success with using TypeKit on many sites.

When I place TypeKit’s embed script in the <head> section of main-template.tpl it throws an error:

System Error

[B]A system error has occurred. Please try your request again in a few minutes.
If the problem persists, please contact Support.

[/B]

I can add it to index.tpl just fine, though.

Any thoughts?
