New Index Family grayed out
I am using Core Capture in the 90 days trial period, I downloaded Capture Designer and tried to configure Advanced Recognition, however, when I open the Index Family Editor in the Recognition Designer, I am not able to add a new Index Family, the option New Index Family is grayed out, Is it necessary to perform an additional configuration before open it? Is this functionality not available in the trial period? Thanks in advance.
PD. I know this question should go in the Core Capture category, however, I a not able to select it, I just can select this category. Sorry.
