Microsoft say this:
Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)
Reasons for this error include a driver that is not present; a binary file that is corrupted; a file I/O problem, or a driver that references an entry point in another binary file that could not be loaded.
Uninstall the driver, and then click Scan for hardware changes to reinstall or upgrade the driver.
On the General Properties tab of the device, click Troubleshoot to start the Troubleshooting Wizard.
That's probably not going to help, but it's the first thing to try...
You could try this too:
Start Registry Editor (Start, Run and type in regedit then click)
Find "UpperFilters" and "LowerFilters" (and "UpperFilters.bak" "LowerFilters.bak", if they exist) value under the following key in the registry, and delete it:
Quit Registry Editor.
NOTE: You might need to reinstall any CD recording apps you have, if they start to not work completely, after doing this.
Don't ask questions, just click my rep tick. Now.
