The new released DVD usually has a new protection. Please first
download the latest version (or new beta version) from
http://www.idealdvdcopy.com/download.htm and install it. Then make
sure you didn't run other DVD decrypters in the background. Those DVD
decrypters such as DVD43 or AnyDVD mostly will interfere with Ideal
DVD Copy to decrypt DVD. So you'd better close them and then re-open
our program to copy the DVD again. If you still fail, please export
all .bup files of the original DVD by clicking "Export bup files" menu
of our program. Then we'll analyze it and update our program to fix
it.
