Are you using the latest version? (All My Books v5.1 Build 1252)https://www.bolidesoft.com/allmybooks/whatsnew.html
According to the "What's New" a lot of sources are changing, and AllMyBooks is changing to meet the challenge.
You could send a request for help directly from your program... AllMyBooks > Help > Support
(which opens a support ticket online with your registration info included.)
This way the developers will be made aware of the issue. I'm not sure how often they visit the forums.
When you do get a solution, please post it here in the forum to help others who may be experiencing the same issue.
