Excerpted from: Explanation of error codes generated by Device Manager in Windows XP Professional (http://support.microsoft.com/kb/310123)
Code 39

Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)

Cause

There are several causes of Code 39 errors:
A required device driver is missing.
A required binary file is corrupted.
There is a problem with the file I/O process.
A driver that is referencing an entry point in another binary file is unable to load.

Recommended resolution


Reinstall the drivers for this device.

Uninstall and reinstall the driver


Uninstall the driver from Device Manager, and then scan for new hardware to install the driver again.

You may be prompted to provide the path of the driver. Windows may have the driver built-in, or may still have the driver files installed from the last time that you set up the device. However, sometimes, it will open the New Hardware Wizard which may ask for the driver. If you are asked for the driver and you do not have it, you can try to download the latest driver from the hardware vendor’s Web site.
On the device Properties dialog box, click the Driver tab, and then click Uninstall. Follow the instructions.
Restart your computer.
Open Device Manager, click Action, and then click Scan for hardware changes. Follow the instructions.

I'm currently having this problem but when I look in the registry I do not find the upperfilter or lowerfilter. There is a lowerfilter.bac but I don't believe that is the one to delete. I have tried the program regcure with no success. What else can be done to fix this problem?

What is listed in device mgr?

When do you recive the 39?

Is the device marked in yellow?

Any changes that either happened or that you perhaps made to your computer around the time that the problem started; particularly any software or hardware that you installed or setup.

I always have this error now. This is what it reads:

Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)

Click Troubleshoot to start the troubleshooter for this device.

It's no longer marked in yellow. It was and then when I ran RegCure and found it was no longer in yellow but I still have the error. As far as software or hardware changes I have not made either except for the Windows updates.

Right click on device and choose uninstall and say OK

Now close all windows and restart PC

See if you still get error and check the upper and lower filters again to see if they are according to the site above
