Widget not showing in Right Sidebar

Using Atahualpa for a CMS with lots of pages with many different widgets in the sidebars. On the home page I used the Widget in Pages with a Custom Menu. The Custom Menu stopped displaying so I got the client to agree to alter the design and position the menu in a right sidebar, and deactivated/deleted the Widget in Pages plugin. BUT the Menu still doesn't show up in the right sidebar. I've combed the forum, checked and re-checked everything. Please let me know what info you need to help me! Thanks!
