This recently happened to me and I discovered........
Check your ASPI files, Use Nero Info......you probably have a corrupt ASPI file.
Find the program "Force ASPI" Google for it
Run Kill ASPI, reboot, run install ASPI, this should give you all 4 ASPI files at 4.60, all the same date. Run Nero Info tool again and confirm ASPI is installed & correct.
Then run Dangerous Bros firmware 111 flasher. Should work fine.
Let us know.
