PDF2HTML@adobe.com service
Has anyone been able to use the pdf2html@adobe.com consistently. For me it works about one third of the time the rest of the time I just get the following error messgae back as an email:

I get this regardless of whether I send the email from Outlook Express on my PC or Snappermail on my Treo 650.

Does anyone know about this or another service that I can use that is similar.
