If you like this program, you should “register” it. The registration levels are explained in the READ-ME file which came with TattleTech. What to do: First, decide how you want to pay. If you have a modem attached to your computer, you can register immediately. Choose Immediate On-line Registration. All you need is a credit card. If you do not have a modem but do have a credit card, you can still register immediately. Choose Order by Phone and the sales representative will give you a code for unlocking the program. If you’d rather pay by check, then choose Order by Mail. With this option, you will print out an order form on paper. Once we receive your payment, you will be contacted with a code for unlocking the program.
