Do you mean that the "Operating System User Account" category under "Extracted Content" has no data or that data typically found within a user account directory (i.e. ntuser.dat) is missing?
In the Tree Viewer at the bottom you should have a Reports section that will contain related RegRipper technical reports that you can check after the module finishes. Also, I'd manually look for those data sources, such as IE history or the user hive, to be sure they're present, then export and test those in a different tool to be sure they're not corrupted.
