custom sidebar pro - will not show second sidebar

I use custom sidebars pro extensively on our site: We have two sidebars on the right of almost every page. Sometime in the last week, the site no longer dispalys any of the second sidebars. I've tried everything I could think of (not much...) without success. I've recently updated WP and Genesis so am guessing an update broke something. I haven't wanted to restore from backup to test because I don't want to lose changes that have been made to the site. Help very much appreciated.
