Robin Hoods Playground

I am following the video tutorial gave on this website for Flashing a Lite-On 83850C drive. My drive was manufactured June 2009. I am able to get Iprep loaded and I follow the command of half open and fully open when after that step i get an error. The program says: File not Found - Key.bin
File not Found - L83DUM.bin
File not Found - ENCKEY.bin

I am unsure if this means the extraction method failed, or if I am missing important files or step. Someone please give me some advice. Thanks.

i know you said you followed the tutorial but what tools are you using? do you have connectivity kit? a via card? on board sata? the more information the better we can try to help you.
