Sorry for the delay.

Since you can send/receive in WLM in Safe Mode with Networking but not in Normal Mode, something is blocking it. I doubt it's your firewall as that should be running in safe mode anyway, but in any case I assume you are accessing WLM through your browser. Is that correct? If so, which browser are you using?

Has anything changed on this computer since you were last able to do this? Any viruses or other malware? Any software installed or uninstalled?

Also, please tell us the details of your system. It helps to know.
