I have reinstalled PokerTracker 4 and need a new registration code.
You should continue using the same registration code that was initially provided to you. If you no longer have the email with your registration code and are registered on the PokerTracker website you can view your code directly on the site under My Account -> Registration Codes.
Your PT4 registration code is good for use on two separate computers at the same time. You should use the same code on both of your computers. If you purchase a new computer, completely uninstall PokerTracker 4 from your old computer. You can then install PT4 on your new computer and continue using the same PT4 registration code that was initially provided to you and is located directly on the PokerTracker website under My Account -> Registration Codes. There is no need for a new code.
