Windows Vista home premium shows invalid product key

[McGrawh]

Recently i had bought a new Compaq Presario laptop, on which i had install Windows Vista home premium with the correct product key. Now just few days back when i tried to turn on my pc, it showed me error message on the desktop screen stating that the product key seems to be invalid one. Then i tried to re-enter the product key but it showed me that key seems to be invalid, and shows the following "0xc004F050" error on the desktop screen. Can any body tell me that how do i get rid of the above issue? Kindly provide me the correct logical solution for the above issue.

2) Then it will open up a internet Browser on your screen, then type: %windir%\system32\cmd.exe on the browser address bar.

3) Then it will open up a window with a black background on your screen.

4) Then you need to type: slui.exe 3 and press the Enter key.

5) Afterwards, you need to type in the Product key from the sticker on back of your computer.

6) After entering the Product key, you need to click on the Next button.

The activation process will complete successfully only if the software has not been previously activated, such as on a different machine. MS Office loses the ability to edit and save files. After Vista's activation deadline runs out, the user can do little other than use Internet Explorer to activate the operating system or buy a new license.
