plextor px-708a

[vipper8847]

I have just purchased a new plex 708a and have downloaded
micrstudio suite 4 I am running windows xp on a dell xps gen 2
The problem I am having is Microstudio does not recognize
my plex or the samsung drive. I have installed the programs
and rebooted the system but still nothing.... I have read that
microstudio 2.508 is the only version that supports this drive
but when I downloaded it gave me the latest version (2.517)
can anyone help!!!:?
