If you are planning to switch to a different device and use your eSpell on it, you need to change registration information. To do that, visit the Clients’ section of DynoPlex’s web site at http://clients.dynoplex.com/eFile/web-access and select “Profile Management”. Then select “Change PIN”. Enter the new PIN then press “Change”. Then register your installed applications through registration wizard as described in the “Confirm Existing Registration” section.
