Catch Fullscreen Pro – Catch Gallery & Essential Widgets Pro not working

Hi Support Team, I've been having issues setting up gallery pages and posts. I followed instructions but I don't get the option of the four styles, nor can I get the fullscreen view of the pictures I insert as gallery option. I then purchased widgets pro thinking this might solve the issue, but I still can't get gallery pages to click through images with a slider. I'm trying to showcase artwork so I really need this to work as shown in your demo. Please let me know how to fix this, thank you for your time! Best, Santiago Suarez
