Believe it or not, I recently encountered similar situations as the OP.
I installed 8.0.1.1 on 9/14 and noticed the Video Converter and File Transfer options said it will expire on 9/17. I have never used both of these options. How can the trial be started? What is also strange is if the Video Converter option has not been used, how can the File Transfer option be used?
Then on 9/17, both of these options were expired even though the day hasn't gone by yet. So I contacted support about this. The first rep said I have 30 days to try. If I want to use it, buy it. And I thought what! After my reply, the second rep suggested that I uninstall and reinstall. Sure enough, today I uninstalled and cleaned out any registry remnants of dvdfab, and reinstalled and no more expired message. So thank you for dvdfab support!!
As for the OP's DVD Copy expired problem, I saw it last night at my relative's house. The same exact screenshots as seen in post #10. He only needs to use the free version, and I thought DVD Copy -> Full Disc mode is essentially HD Decrypter option. So something is definitely screwy here. I get really annoyed that merely clicking on Full Disc will pop up the message. I think it would make sense that this message should pop up when you click on the Start button before ripping or converting process begins. Well, I brought this up with support as well. Hope they look into it.
@brendon7800, perhaps you can redo a complete uninstall within Windows uninstall program list, including cleaning the registry remnants left by DVDFab using CCleaner, then reinstall. Hopefully this will straighten up the mess. I will ask my relative to do the same thing as well. I
