Pinnacle Instant Copy 8 - Access Violations

Hi, I wonder if anyone can help me?

When I try to copy DVD+RW discs containing video to my hard drive or onto other DVD+RW discs (using Instant Copy 8 & my burner) I keep getting - “Access violation at address 012F3E13 in module ‘vobscr.ax’. Read of address 00000000.”

What does this mean & how do I get around it?

Thanks
