Can't test write in Microstudio2.611 using new Plextor PX-716UF

[aklarry]

Hello again,
I tried a Diagnostic Start up Through MSCONFIG with a Safe Boot, This only loads the files needed for the Operating system to work and nothing else.
I also turned the speed down to 4x in MicroStudio
MicroStudio still gives me the same error, therofore i can't test write or write to a CD.??????
I bought the burner that was recommended and sold by MTU.
The Plextor PX-716UF (external) and bought the MTU
This set up was supposed to be guaranteed to work if bought from MTU.
But all i've got so far is a challenge to try to make it work. Needless to say, I'm getting my butt kicked because nothing has worked thus far. I'd like to think that i am pretty knowledgable in computers, but this program is making me feel like a newbie.
I still could use the help of some magical Guru that might be able to help me with this problem! But please read through the posts so that you know what i've already tried.
