Same problem here...intermittent. Happens on my desktop machine (XP MCE 2005) but not on my notebook (XP Professional SP2). I've contacted Nero support and the email exchanges are still going on. Their first suggestion, using the Nero Clean Tool, didn't work and I'd already tried that before contacting them. I don't like to use that tool because it screws up other applications that have burining capabilities and they all have to be reinstalled (iTunes, Clone CD/DVD...)
Here's the first email response from Nero...
Dear valued customer,
thank you for your email and your interest in our software.
Please try the following:
1) Delete Nero 7 with our CleanTool.
2) Reboot your system
3) Download and install the latest version of Nero 7
4) Reboot your system
Please delete all Nero 7 applications off of your system using our special Nero 7 CleanTool.

Launch Nero StartSmart and open the Nero ProductCenter by clicking
on the "Nero" logo in the upper left corner.
Select the "Serial Numbers" tab to view your serial number.
Alternatively, you can also find your serial number as follows:
Open the Registry by clicking on "Start" in Windows, clicking on "Run", entering "regedit" in the text field, and confirming with "OK".
Now select the path
Double-click on the "serial7" entry.
Your serial number can be found at this location.
The serial number is structured as follows:
When you have your serial number, proceed to download the Nero 7 CleanTool using the following link:
Save this file to your Desktop.
Unzip the CleanTool with WinZip or WinRar and double-click on the .exe file.
Reboot your system when the CleanTool has finished.
The Registry will have been cleaned and all Nero entries removed.
Should you have any other request, please don't hesitate to contact us again.
Here is the second email. Everything was fine with all the settings/files they had me look for:
Thank you for your e-mail.
Please provide us with more information so that we can properly assist you.
Does the file "incdsrv.exe" exist in the InCD installation path ?
