Maybe I am the only one who had this problem but here is what I did to resolve this. When I got the error message I went to the Firmware Tool 32 tab and selected "Open Source Firmware" which I pointed at the original Sammy firmware that I had saved. Then I selected "Open Target Firmware" and pointed at the new Sammy LT-sammy-v2.01.bin firmware and then selected "Spoof Source to Target". The keys then agreed and I wrote the new Sammy v2.01 CFW to the DVD drive and it seems to work.
If this was unnecessary to do this to get it to work then I must have done something wrong initially. What was it if I did?

Actually I figured it out on my own prior to reading the responses which I appreciate.
