I need help.

I have recently puchased Microstudio 2.60. I have a Plextor CD-R PX-W4012A 1.04 Writer. I installed both programs. When I click duplicate disc I get the message - select a reading devise (CD ROM). I have in the reading and writing drive the above Plextor. The ASPI driver is setting on Default Driver. I copied one CDG and it worked, I went to use it again and it would not work. I tried reinstalling the Plexiwriter and the Microstudio program. What am I doing wrong?
