I keep getting an error in my log file saying:Logical unit Region has not been set! What does this mean and how can i fix it plz help me
I don't know personally, but if you head over to www.DVDdecrypter.com you can post the question in the dedicated forum. In my experience you will get an answer pretty quickly from the developer himself.
If you have powerdvd installed, stick in an original disc, play it - it will probably display the region window - select the correct one and close. Then retry in dvd decrypter, this happened with my new dvdrom recently - and this cured it..... There are probably other ways but this is the one I used.
