DVD copy Access Violation error message

I installed an unlimited version of DVD Copy. I use this one for copying and for back up videos to my computer at home.
When I copy a video I get this error message. I tried to copy the video again but the error still pops up.
I tried to re-install the program but the error still there,
what am I going to do?
