Method 1: Just start SofTest on your computer. The opening screen will state your registration status. It should state "Complete".
Method 2: Go to http://www.examsoft.com/pepperdinelaw. Select the Exam Takers button at the bottom. Choose Confirm Registration from the menu. You will need the ID and password that you used during installation (the ID and password were also emailed to your Pepperdine email account).
(Optional, yet recommended) ExamSoft has posted a "Mock Exam" to provide you an opportunity to experience downloading, taking, and uploading an exam administered in secure mode using SofTest.
When you register SofTest, you will be notified on-screen that there is an exam file available for download. You may download, take and upload the Mock Exam at your convenience up to two times.
