Weather Watcher stopped

The program stopped updating last Thursday evening. I have updated to 5.6.1 but it is still not updating.

I have tried from various locations (none of which require a proxy) but with no luck.

I can access with no problem. I am NOT aware of any changes I have made to the system to cause it to stop.

I am using ZoneAlarm and I have set both Weather Watcher and the DL to trusted and allowed access to the Internet and as a server.

Any ideas what may have happened.
