Titanium Backup: How do I apply the lisence?

[Guest skydart]

I have just purchased the Titanium License. How do I apply or enter the lisence to get access to all the goodies is allows for, like "Market Doctor", etc? In other words, how do I activate the free version? Please advise.

UPDATE: I received an e-mail with the license key with instructions.
