I have found ASPI 4.6 at this site.
http://www.musicex.com/mediajukebox/aspi.html
There also is a download for 4.7 on the same site.
After successfully installing 4.6 I am presented this message:
Error: Unable to find a known CD-Recorder device!
Verify results and press any key to return to Windows.
Press any key to continue . . .
I have successfully burned 8 CDs, both data and music using Nero 6.0. I am awaiting help from all.
