If you are planning to switch to a different device and use your eCell 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 the registration wizard, as described in the “Confirm Existing Registration” section.
