I had Vegas Pro 19 working fine. Just completed an update and now it won't launch with the "activate & register online" button the only option. When I chose the option it quickly opens a window it cannot get online. I'm online with antivirus suspended but no luck. I've tried the reset internet options link which does not help. I've also checked the serial number is the same as when I purchased it in August and its already in the registration database. How can use the software I paid for?
