I just purchased and installed Vegas Home Studio platinum 11 build 247 and when it says ok the next step is to register, I click next and a small white screen then displays looks like something is loading up except nothing happens, HELP!
If I had this problem I would contact Sony Support. You get free support for 30 days, if I'm not mistaken, and they would be the best ones to address this issue.
If it's not connecting online, it's usually a firewall or antivirus interfering.
Click on the button for telephone registration instead, and register manually.
