First, this GenForum is about the Online Data Collections at Genealogy.com. Perhaps the Using or Search GenForums for Family Tree Maker might have been more appropriate. However, please do NOT repost your question.
Your message is not clear. However, I will take a guess that you are trying to use Family Tree Maker version 16 to find Hits at Genealogy.com and it's Online Subscriptions. If that is your question, the reason for that is, Version 16 uses the Online Subscriptions at Ancestry.com and NOT at Genealogy.com.
Please provide some details, if I missed your question.
