Thank for your feedback here and sorry for the inconvenience.
If you downloaded the DVD Decrypter and run it before running the DVD Ripper but not working to load DVDs, we recommend you to go DVD Ripper HD->Preferences, change the DVD loading mode to use special mode. Then save the settings to restart Leawo and re-load. If still not working, could you try more DVDs and tell us the result. If you just can't load this DVD, please go to your DVD VIDEO_TS folder, find all the IFO files and compress them to send to firstname.lastname@example.org
then inform us here to follow-up.
