Welcome to forums.
First, run, don't walk and dump NORTON. Do it now. The faster the better.
Get a free firewall and configure it to allow the Southwest Program to have access to the Internet/Network. The two best firewalls are:
Kerio and Sygate
Get yourself and AV that along with being free puts out updates faster than Symantec and uses much less system resources:
Avast and AVG
Uninstall the Ding program.
Re-install the program and make sure the firewall allows it to access the Internet. Disable the stupid Windows firewall.
Let us know how it goes.
No two moments are alike and a person who thinks that any two moments are alike has never lived.
