Vist 64 bit and Plextor PX-712UF

[Kuurus]

I have recently upgraded from Vista 32 bit to Vista 64 bit SP1.
I have been using a Plextor PX-712UF with MTU on Vista 32 bit but am now having some
issues. I am using the latest software version of Microsostudio.

1.) I am unable to copy CD-G track from the Plextor to Hard drive. The drive is funtional
from Windows Media Player in that I am able to play the audio track portion just fine.
The problem is when Micrstudio software is involved.

2.) Existing BIN files I had made prior to the Vista 64 bit upgrade show the graphics but no sound

I keep hearing that there are drivers for the Plextor on your site but don't know the
link.

Can you folks help me out?
