If you do not have a license for Time Shaper, you can purchase one online. Time Shaper will run with a fully-functional 31 day evaluation license when first installed. When running in evaluation mode, a window will appear indicating how many days are remaining in the evaluation. If you have a license, you can click on "Enter License Code", otherwise click "Continue Trial" to keep using the software.  

Enter your activation code when prompted, and click "Check Code" to validate the code with the server.  If this is the first time you've used this activation code, you will be prompted to enter your email address.  This email address is used to send validation codes for deactivation and reactivation of the license code. Click "Activate", and the license will be activated with the server.  

If you have used this activation code previously, you will need to validate the code with a passcode sent to the email address you used when you first activated the software.  When you enter your activation code and click "Check Code", an email will be sent to your email address with a six-character code. Enter this code into the "Passcode from email:" box and click Activate.  

A single activation code can be used on one computer at a time.  A license can be deactivated on one machine to be moved to another, and two deactivations/reactivations are allowed per 30 day period.  To move a license to a new computer, first deactivate the license on the old computer by selecting "Registration" from the "Time Shaper" menu and then clicking "Deactivate License".  It is not absolutely necessary to deactivate a license before using it on another computer, but only one such move is allowed before the license enters lockout, so it is best to deactivate the license if possible.  

Again, a passcode will be emailed to the email address entered when the license was first activated.  Enter this passcode and click "Deactivate", and the license will be removed from this computer and is available to activate on a new machine.
