Firmware for PLEXTOR CD-R PX-W1610A???

I have a PLEXTOR CD-RW which has given me no end of problems.

I did a Google search for updates to the firmware and found that I have one of the oldest versions of the firmware. It seems as though PLEXTOR has fallen off the Earth----a very long search just gave information about versions (with no
downloads available)---- hunting for PLEXTOR sites give a 404 response.

Any help out there?


Thanks in advance,
