Copy of a copy error?

i am trying to make a copy of a copy using DVD Next Copy Version 3.04.4, when i attempt to select the DVD in “source” it attempts to analyze the disk and then comes up with an error, saying “cannot access data or source is empty”. any help would be greatly appreciated. thank you

If the copy was burned too fast or was burned on bad media then this can/will happen. Just use the original and use verbatim media and burn at 12x.
