Nero fast burning plug-in for media player and LiteOn 411

I’m having problems with my Nero fast burning plugin for media player. When I try to burn with my Lite On LDW-411, it tells me “device could not be opened.” However, I can burn with my older Yamaha 6416 Scsi. This is on Win2k, Win Med Plr 9, and latest plugin. Both alcohol and clonecd work fine with the 411. Ideas?
