First, you should expect to now receive spam overload as you are using this email address as your SN here, this forum shares these posts with many search engines in real time and email harvesters are hard at work gathering them - btw - if this is also the email address associated with your wordpress.org site, you have now revealed it to all.
That said, please list your Version of WP, your Version of WLW, and if you have confirmed that XML-RPC is supported by your web host (and turned on in WP settings)
