New MTU Plextor Burner Not Reading or Writing

[bjswaim]

I received my new MTU Plextor PlexWriter 48/24/48u (USB) cdg certified burner yesterday. I plugged it in and Microstudio recognized the drive with no problem. It read the first disk perfectly. Then I started writing the files to cdr and received an error message. Now, it doesn't read nor write at all. The error message is as follows:

"Error: 'TEST UNIT READY' command failed on device 2:0:0
Unexpected ASPI error (04h00h00h)"

The Microstudio write window states that the "CD Burner is not ready"

I checked to make sure that the mtu aspi driver was chosen and also checked that the product version is 1.20.

Please help!!! Have no clue what to do. Need this to be up and running sometime today.
