Cannot seem to find the amulet

Hello, within Book I's main quest of finding your amulet within the Crypts, I have checked everywhere inside the crypts, and read up on a couple walkthroughs as well. Despite these efforts, I failed to find the amulet in any of the crypt rooms, or even the security room. Has anyone experienced this problem? Whether or not you have, do you have any suggestions on how I may resolve my issue?

Thank you,

-Jim
