Nero InfoTool Problem, Help Please!

I have Nero 6 Ultra Edition installed and it automatically installs Nero InfoTool. I have used it successfully until I did the 812s to 832s firmware update on my DVD burner. I have a Teac drive which is just a re-branded Lite-On 812s. The drive works perfectly and I have no other issues, but when Nero InfoTool tries to scan this drive for information, my PC reboots. I checked Event Viewer and I have no related errors, nor do I have any errors showing up when the PC reboots. In fact, I have my PC set not to reboot on unrecoverable errors. I would really like to sort this out if anyone can help me.

Thanks.
