Lightscribe problem with Nero

I have a Samsung SE-S184M DVD burner (burns DVD+R DL and Lightscribe) with Nero OEM software. I have already installed latest driver update from Samsung. Have PC with Windows XP Home.

The problem is that after burning one Lightscribe disk, a second can’t be burned because Nero reports no Lightscribe drive attached – ditto the Lightscribe Diagnostic Utility. The burner can burn DVDs OK but not Lightscribe.

Rebooting restores the Lightscribe function for one more burning, then once again no Lightscribe burner is found.

Any remedy?
