Welcome to the Community, Rayvet.
 

QuickBooks 2008 is a discontinued version of our product. Because of this, you won't be able to register it online. You'll need a validation code to re-register your program. Intuit makes every effort to provide support for registration/licensing, however, successful registrations, providing key codes, etc. can't be guaranteed for older versions.
 

You'll definitely want to get in touch with our Customer Care Team to discuss this further. They'll be able to pull up your account in a secure environment and go over what options are available.
 

Here's how you can contact them outside of your books:

1. Go to our Contact page.
2. Choose QuickBooks Desktop.
3. Click Continue as a guest.
4. Pick your version.
5. Hit Search for something else.
6. In the Tell us more about your question: field, enter a description of what you're contacting Intuit about.
7. Press Search.
8. Select Start a Message.
   

Be sure to review their support hours so you'll know when agents are available.
 

I'll be here to help if there's any other questions. Enjoy the rest of your day!
