BenQ DW 1620 won't burn using Nero 6.6

My BenQ DW1620 is not working correctly at all!!! I purchased the Generic version, and it worked fine until I upgraded the firmware to the real DW 1620. Now I get the following when I attempt to write with Nero:

5:19:24 PM DVD-Video files reallocation started
5:19:25 PM DVD-Video files reallocation completed (no file modified)
5:19:25 PM DVD Video Files sorted
5:19:25 PM Caching of files started
5:19:25 PM Burn Process started at 16X (22,160 KB/s)
5:19:25 PM BENQ DVD DD DW1620
Book Type automatically set to Current recorder setting
5:20:12 PM BENQ DVD DD DW1620
Session fixation error
5:20;12 PM Generating DVD high compatibility borders
5:20:12 PM Generating DVD borders completed successfully
5:20:12 PM Burn process failed at 16X

When I start the process, I hear the drive spin up and start, but after about 30 seconds, it spins down and I get the error as described above. I have tried to start it @ 8X and 4X to no avail. I am using FujiFilm and Memorex 8X DVD+R media

Can someone please help?

reinstall nero.

use the NERO CLEAN TOOL after you uninstall it. then reinstall NERO. you can find the clean tool at NERO’s website.

Thanks. I will try this when I get home.
