Hi, Lack of knowledge is one thing, lack of common sense is what brings me here before you. Yesterday I installed the adaptec aspi drivers 4.71.2, and when I tried to use Intervideo's DiscMaster2 it didn't work. Everything else is working fine, I can play music discs, dvds, and other burning software is working fine, except the DM. I tried uninstalling and re-installing it, but it doesn't work. I then checked the device manager and found an admiration mark in the scsi controller. Is there anything I can try to fix my doing? Thanks,
