This may not be exactly the same as your situation but give it a try.
Q9. I installed Adaptec Easy CD Creator in my PC, I had uninstalled and install new writing software - Nero, but I always get fail writing job.
There are some software conflict issue between Adaptec Easy CD Creator and Nero, even you have uninstall one of them, you still can't avoid this problem. Please make sure that this driver CDR4VSD.VXD and SCSI1HLP.VXD is removed from the IOSUBSYS directory and then reboot. Then this problem should disappear
