Hi, boc,
1. In order to remove the protections, DVDFab "Blu-ray to Copy" need connect internet to decode AACS and BD+ copy protections. As the reasons, please refer to for the detailled explanation.
2. Please open "Conversion settings" window, click on "General", then, click on "Network" to change the internet access to "Direct connection to the internet" to make your DBDFab internet accessible.
If you want to use proxy address, please set "Manual proxy configuration" in "Network" setting window.
By the way, dvdfab.com is not down, try again to see.
Sincerely Yours
Malcolm Wang
