Help with liteon lvw-5005


I’ve just received a 5005 (I think, since it says 5001 in top right on front, but has an AllWrite sticker across the top and came in a 5005 box).

I couldn’t download the firmware from the Liteon site (invalid serial no - 0090) but eventually managed to get hold of LNFB2075.E00.

However, when I load the cd I get ‘reading-data-open’ and the cd ejects. If I load the cd with the system menu on, I get ‘file’ displayed.

Can someone tell me what I’m doing wrong? How should I burn the CD with the firmware on?
