Richard: Can you describe the problem in detail?
Have you looked at the logfiles as I suggested? If you don't see anything wrong there, I'd be happy to take a look to help you out. The cert request is transferred over http. If you're using Windows, and have multiple protocol-specific proxy servers defined, submission of the cert request will fail; you can fix this by specifying only an http proxy (temporarily removing the other proxy server specs).
