Hi The Kray,
 
 
The error 0xC004C008 means that the key has exceeded the activation limit and the activation server determined that the specified product key could not be used.
 
 
If you have trouble activating Windows 7 open the Windows Activation Wizard while in Windows 7 to use the phone and activate Windows:  
1. When you reach the desktop click Start, then in the Search box type:  slui.exe 4  
2. Press Enter on your Keyboard  
3. Select your Country.  
4. Select the Phone Activation option, then call the number given .
 
You may have to call PA Call Center to activate the system.
