I just moved last week and on my new connection it won't let me sign into WLM. I keep getting error 80072745.
It's definitely the connection cause it used to work on my old connection fine before the move so it's not the firewall.
The connection is a LAN but changing proxies and other stuff is beyond me. When I run troubleshooter it says error with the Hosts File. I can use YM only on "firewall with no proxies" settings.
