Oh, sorry, I forgot you couldn't see everything that I do.
Basically, your XML-RPC file is returning a 404 not found error for us, which usually means that they're blocking it (or us) for some reason.
Are they noticing anything in the server access logs that might help?
Basically, try connecting Klout or Jetpack again before contacting them, so you can provide them with a specific date and time.
