Nero 6 Hd-Burn DD0401

Hi, I have a Iomagic DD0401 with Hd-burn activated. The drive comes with Nero 5.5 and I can burn cds with Hd-burn without problems, recognizes my drive with this function.

I downloaded the new Nero Demo 6, and this version dont recognizes the Hd-burn function in my DD0401. I want to upgrade to this version, but without Hd-burn I dont think so. Nero 6 says that my drive is not HD-Burn drive. I had to reinstall Nero 5.5.

If anyone can help, thanks in advance.

Perhaps the reason is that it is a demo?
