Hello what I am about to post is an actual copy and paste from the Microsoft knowledge base.
Some parts may refer to an OS your not presently using, however the upper and lower filters are the same in the Windows registry of Operating systems from Windows XP and up to Windows 7.
(UPPER AND LOWER FILTERS ERRORS)
This problem may occur if one of the following scenarios is true:
∑ The filter drivers in the CD and the DVD storage stack are not migrated successfully to Windows.
∑ You uninstalled CD software that fails to properly remove itself in the registry.
∑ You installed software that adds filter drivers in the CD and the DVD storage stack that interfere with existing filters.
To resolve this problem, remove the affected filter drivers. To do this, follow these steps:
1. (In Windows Vista and Windows 7) Click Start, type regedit in the Start Search box, and then click regedit in the Programs list.
(In Windows 95, 98, ME or XP. Click Start, then RUN and type regedit into this field box.)
If you are prompted for an administrator password or confirmation, type your password, or click Continue.
2. Locate, and then click the following registry subkey:
Caution There can be many instances of the registry subkey that is mentioned in step 2. You must make sure that you are in the appropriate registry subkey before modifying the UpperFilters and the LowerFilters values. To verify that you are in the appropriate registry subkey, make sure that the Default data value is DVD/CD-ROM and the Class data value is CDROM.
3. In the right pane, right-click UpperFilters, and then click Delete.
4. Click Yes to confirm the removal of the UpperFilters registry entry.
5. In the right pane, right-click LowerFilters, and then click Delete.
6. Click Yes to confirm the removal of the LowerFilters registry entry.
7. Exit Registry Editor, and then restart the computer.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:http://support.microsoft.com/kb/322756/
These filters can cause a CODE 39 error to pop up.
Also Error codes from Windows are listed at this Microsoft web site.http://support.microsoft.com/kb/310123
Please ignore the reference to an operating system that you may not be using, as the errors codes apply to Windows XP and up.
Here is a copy and paste of ERROR CODE 39
Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)
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.
If this does resolve your problem, try disconnecting the data cable from the device and plugging it back in again, sometimes this helps resolve a problem with a faulty connection.
Make sure device is recognized by the computers BIOS setup utility.
Hopefully this will help.
