Hello & welcome to SevenForums,
Adaptec ASPI drivers v4.70 are discontinued and was working till XP.
Most of the actual software do provide a LowerFilter & Upperfilter bynow.
The updated BonkEnc link is: fre:ac - free audio converter
Checking the CDRom in the "Device Manager" might help.
One thing i used to do is is first Unactivate the device then reboot seeing if it activates again (might need to do it manually after the boot)
Uninstall the device CDRom from the "device manager", then rebooting does load the drivers.
