HP DVD840 and CD Speed

I recently installed an HP dvd840 Lightscribe drive in my computer, which came with a NeroToolKit which included a copy of CDSpeed2000. However, when I try to do a disk quality test, the following results come up:

All zeros. When I try to do a disk scan, the program crashed immediately. My other drive is a Lite-on. The disk quality test works ok on it, but the disk scans come always come up looking like this:

With the scan crashing the system before it finishes.

Nero, as well as the CDSpeed2000.com website have been as helpful as a box of rocks. If anyone knows whats going, I’d sure appreciate it. Incidentally, older versions of CD SPEED will work on the lite-on fine, but no look on the HP. Thanks for the help…
