The weather forecast not showing up?

Hi there,
I have been having the problem like the weather forecast not showing up. I have got the latest version and it is still the same. When I click on open weather watcher, nothing is happening…wonder how can I have the weather forecast box show up. It worked for a while when I first install the program many months ago and since then, this problem remain.
I would really appreciate for your assistance.

best regards,
Kelvin
