CD's Won't Burn?

[buttonpusher]

I just recently upgraded to the new external CDR-DVD burner and the new Karaoke Suite 4 - Microstudio 4.001 software. All seemed well until I tried to burn the songs to a CD. I've been using the recommended Sony CD-R CDs but it's not working. I lowered the speed to 4x and tested the CD -- worked fine. But when I tried to actually write the files I get a "Write aborted by the user." I've looked on the website and found "near" solutions to the problem, but haven't seen this particular one. My computer has the Windows XP.

Any recommendations?
Thanks!
