I am trying to upgrade my Pioneer 107D firware using the DVRFlash utility with the latest firmware. When I load MS-DOS and entered the information as instructed. I get a Pioneer "disclaimer" come up asking if I agree. After entering Y for "Yes", I get a message "// sptxOpen.CreateFile: x2 (2) The system cannot find the file specified. Could not open device \\.\E: I have tried several times, same thing comes up. ANy ideas on what I should do to get this firmware to load?

I am using Windows 98SE.
