I am getting Error 3204 0x8DE20003, cannot send or receive.

This seems to be a very common issue, yet no publically available solutions, meaning some backend server settings, so a post stating that you need to contact support and ask your own question to get it fixed would be helpful for people looking for a resolution.

 

Running 64-bit Windows 7...the problem just inexplicably starts.  I've run the repair function from the Programs menu in the Control Panel, logged out/logged in, etc.
