Make sure all other programs are turned off or disabled. What burning app do you have installed on your PC?

 

i have nero 6. thanks for your help

 

Do you have InCD installed with Nero?? If so get rid of it and try again. Here is a tool from Nero that will make sure it is gone

hi i ended all apps. i uninstalled incd but still get the same error. i also have dvd x copy. do you think that is the problem? thanks

 

You could try re-downloading the flash program just incase its a bad file you have. Do make sure though that programs like your antivirus are stopped before you attempt to flash an EPROM chip.

Don't know if this page may be of any use to you..
