I found this at the Microsoft website but I'm not sure if it will help:
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.
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 vendorís 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.
