Unlocking UltraSeps is simply done by purchasing UltraSeps Version 3 and running the installer with Photoshop closed.
Following install, open Photoshop and load the Version 3 Actions.
UltraSeps will then be functional on your system.
Tip On Loading The New UltraSeps v3 Actions:
A good idea is to CLEAR your Actions Panel first (if applicable), followed by loading the new Version 3 Actions to be sure you’re not using the old actions if an earlier version of UltraSeps was ever used. Clearing the Actions panel of all old actions is done by clicking the small icon in the top right corner of the Actions Panel (which looks like with 4 small lines) then selecting “Clear All Actions”.
