Windows 7 64-bit 0xC004E003 error when validating registration code

Question

I am the original owner (2010-03-31) of an ASUS K0IJ laptop that came with Windows 7 64-bit pre-installed.
Windows 7 has run properly for almost exactly two years.  As of this afternoon, I suddenly began receiving "This copy of Windows is not genuine" errors.  Yes, errors  — I am the original and legitimate owner of this computer and
its OEM disc.  I also ran the registration process when I first purchased the computer.
Running WindowsActivationUpdate.exe did not correct this problem.
In Computer —> Properties —> Windows Activation, the "Supply a Different Activation Key" tool will not accept the original OEM license key that has worked for two years. 
If instead I try using the other W7 serial number I have for this computer, I receive the aforementioned 0xC004E003 error.  Moreover, the process does not offer me any other working options such as phone registration: I instead get caught in a "site
loop" where I am referred around and around in a circle to the same set of three or so unhelpful pages.
The MGAdiag.exe tool returned the following:

At the risk of stating the obvious, I'm not only frustrated, I'm angry. I am the original owner of this computer which I purchased from a legitimate dealer, and the computer is running the instance of Windows 7 64-bit that came with it.
Why is Microsoft subjecting me  to this insult and aggravation?
Sincerely,

Answer 1

Are you reading the activation key correctly? Did you call Microsoft or Asus and ask them about the problem. You can also set the laptop back to factory specs (But will lose everything you put on it after you bought it) and it should self activate. I'd be
on the phone to Asus and if that doesn't help call Microsoft.
Found the following on the internet.
The problem appears to be in the Licensing Store - please try the following.....
Recreate the Licensing Store with the correct data.
1)Go to the SYSTEM32 folder on the C drive
2)C:/Windows/System32
3) Find the file CMD.exe
4) Right-Click on CMD.exe and select 'Run as Administrator'
5) Type: net stop slsvc (it may ask you if you are sure, select yes)
6) Type: cd %windir%\ServiceProfiles\NetworkService\AppData\Roaming\Microsoft\SoftwareLicensing
7) Type: rename tokens.dat tokens.bar
8) Type: cd %windir%\system32
9) Type: net start slsvc
10) Type: cscript slmgr.vbs -rilc (It may take a long time for this to complete, please be patient)
11) Restart your computer twice. 
You may be asked to enter your COA Key and/or Activate. – if asked for the Key, use the one on your COA sticker on the machine’s case
