PHILIPS DVD+-RW DVD8631 is missing/disabled/not recognized

I recently reinstalled my operating system. I've filled in all the yellow question marks and did it in the appropriate order. The only issue I have is:

* within Device Manager > under DVD/CD-ROM drives> a red " X " is located the on PHILIPS DVD+-RW DVD8631driver.

The device status is:

---

This device is disabled. (Code 22)

Click Enable Device to enable this device.

---

But enabling the device doesn't work. I went into the BIOS to see if it was turned off mistakenly but it is on. I have the driver from my specified downloads but it can't run because the computer can't detect the E drive which holds the Philips DVD/RW driver. The only one detected is the D drive. How can I get my computer to detect it so I can update its driver?

On this page: http://www.tomshardware.com/forum/171067-32-drive-drive-detected, they say to do some stuff but I not sure about it and if it applies to XP.

Start the Run Command Prompt

Type in "regedit" without the parrenthesis then click ok

Go to HKEY_LOCAL_MACHINE

Then SYSTEM

Then CURRENT CONTROL SET

Then CONTROL

Then CLASS

Then find {4D36E965-E325-11CE-BFC1-08002BE10318}

The whole thing looks like this:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

Then delete the upper and lower filters....

Then restart your computer.
