I haven't updated to version 9 . It might be a firewall or antivirus problem . You need to allow permission for the connection.
I probably won't update to version 9 unless I'm forced to. The license check every time I use DVDFab is a bit too much for me. I wonder what other information DVDFab probes for while it is doing the license check.
For right now DVDFab v8 is fully updating so I will use it.
