Microstudio write disc

[joe's jams]

OK, I've clicked on the WRITE DISC but where are the *.tst files I'm supposed to have created when I clicked the ADD TO WRITE LIST button on the play screen...I clicked on OPEN lists in the WRITE DISC FROM popup window, and there is nothing there.

I've also tried to use the ADD SONGS button in the WRITE DISC FROM window, but I don't have bin & wave files.
