Upgraded from Vista to Windows 7 and can not get Echolink to work. Echolink connects with proper display etc but Fire Wall test fail. Using Norton 360. All configurations say it is good (Allow). Tried reinstall Echolink. Help says UDP may be blocked or router problem (no router) but can not find where. I am using PDA net as a modem with Moto Droid via Verizon Wireless. It all worked well before upgrade to Windows 7. Been a year now and can not find answer. Friend says Verizon may be blocking. Any suggestions?
