Missing Fonts when calling Output ES

Hi. I have tried implementing the Output ES Generating a PDF document quick start and I'm getting the following error from the XMLFormService

2007-08-08 14:58:30,796 INFO [STDOUT] Caused by: com.adobe.livecycle.formsservice.exception.FormServerException: XMLFormFactory, PAexecute failure: "(com.adobe.document.xmlform.ReturnStatus@25edb3) Font ArialNarrow-Bold is not found on system."

My system fonts directory seems to be set up correctly in the adminui, under global configuration.

Is there something else I need to do to get this to work?

Thanks,
Bryan
