Hi! I have a system I built a few months ago, that worked fine until now. My Computer suddenly stopped seeing my Optiarc dvd-Rw (Sata) after installing Roxio 10. (could be a coincidence ) I uninstalled the drive and reinstalled it but I get a message that it was unable to load the drive , or the driver may be corrupted or missing. THis is on Vista Home premium. I downloaded the driver to try it again and got the same result. WHy? thanks in advance for any info. NV After writing this I found the other posts with the same problem. Error 39 so I will check those out tonight. Sorry for not checking first.
