I’m using Windows 8.1 but having the same issue getting error code 630. Actually I was able to download and begin a return. It’s when I came back a couple of days later and tried to log in that I was prompted for the license key again and received the error. I’ve spent 2 hours on phone with TT support and still get the same error code. Even tried a completely new download with key code and still received same error. I’m going to try another computer next and see if that works. And possibly try using internet service at work so check that too. SO frustrating!!!!!
