Windows 8.1 Activation Error 0xC004C003

Question

Hello. I have a HP ENVY 17t-j000 Quad Edition CTO Notebook PC and recently I have been having many problems with it and things were constantly messing up so I decided to back up all of my files and restore my computer to factory settings. After I had done all of that I logged in for the first time and since I bought it with Windows 8 pre-installed that was the OS that it was running. I looked at the bottom right side of my desktop and it said Windows 8 Build 9600. I also went to my PC settings to personalize my computer (change the lockscreen picture and whatnot) and it said I had to activate windows first. I went to the tab that said activate windows and it said something was wrong with my product key (I cannot remember). Then after that I decided to just update to Windows 8.1 via the Windows store application in my start menu. After I updated to Windows 8.1 it still had the watermark on the desktop but it now said Windows 8.1 and Build 9600. I went to the tab that said activate windows and it said "This product key doesn't work. You might need to get in touch with the store or company you bought Windows from, or you can buy a new key from Microsoft."  Farther down on the page it had a place where I could click on error details and when I clicked on it, it said "Error code: 0xC004C003 Error description: The activation server determined the specified product key has been blocked." I looked up how to fix this error code and on the windows support page it said to contact the company you purchased your system from and request help or a new product key or have them look it up for you. If I could get help on getting this fixed it would be greatly appreciated.
Thank you,

Hi LChelcun
I'll try helping you,
This issue occurs because the incorrect permissions are set on the Tokens.dat file or this file is corrupted.
Try this:
Click Start, and then type cmd in the Search box.
Right-click cmd, and then click Run as Administrator.
At the command prompt, type the following command depending on the operating system and then press ENTER:
icacls "%windir%\ServiceProfiles\LocalService\AppData\Local\Microsoft\WSLicense" /grant "
(between icacls & "%windir% there is a SPACE)
{Now, The correct permissions for tokens.dat should look like this output from icacls:
tokens.dat NT AUTHORITY\SYSTEMI)(F)
BUILTIN\AdministratorsI)(F)
NT SERVICE\WSServiceOI)(CI)(R,W,D) }
Close the Command Prompt window.
You must type this command from an elevated command prompt.
OR
To fix this problem automatically, click the Fix it link given below. Then click Run in the File Download dialog box, and follow the steps in the Fix it wizard.

Notes:
This wizard may be in English only. However, the automatic fix also works for other language versions of Windows.
If you are not on the computer that has the problem, save the Fix it solution to a flash drive or a CD and then run it on the computer that has the problem.
Do not run the automatic fix on the machine that does not have the problem.
The automatic fix will not rename the Tokens.dat file for you if tokens.bar already exists.
RESTART SYSTEM.
Hope this resolves your issue,
thanks,
