Once you've paid for your new SignCut Pro 1 subscription period, your existing SignCut license that you entered during your purchase will be extended. To get up and running again with SignCut, make sure your computer is connected to internet then restart SignCut and the expiration date will be updated and SignCut will go out of test mode.
If you have subscription time left on your license number the new time will be added to the existing time. You can check your new expiration date in the calendar shown by clicking on "About SignCut" in the help menu in SignCut.
