If one of your users cannot login to Mortgage Manager, it could be because of multiple errant login attempts, which can result in having the user account locked. To check whether this is the case and to resolve the issue, open User Manager from the Admin Tools Menu Group (Figure 1):

Click on Find Now (Figure 2):
