Nero kills multisession

Hi, I been having a problem with Nero 6 and 7, and normally had no problems with continuing a mulitsession with my dvd’s. But for a few days now, when ever I continue a multisession with a dvd it writes the files to the disc and says successfully complete without an error message, But when I check the dvd the data has not been added and I cant continue multisession.

I have a Lite-on SOHW-1633S with Firmware: BS41
I been using Philips DvD+R but I have had this problem with over mediums too.
Been using Nero Version and

Other specs:
2ghz Intel cpu
512mb ddr ram

Thank you in advanced :slight_smile:
