HP a1020n - Lightscribe (Label Program AutoStart)

Had my desktop for 2 years, and up until about 3 weeks ago, anytime I
completed a DVD-R or CD-R burning project (using any burning program), my
Lightscribe labeling program would automatically start-up, and would import
my burnt list....so that I could lightscribe the disk---without having to
re-type everything. Does anyone have any idea how that automatic feature
was disabled...or, how to re-implement it??

Thanks....Regards, John
