Plugin is NOT even showing after activation

Hello,
I just installed this plugin and was FINALLY able to activate it (I was getting a fatal error upon activation attempts), but NOTHING shows up. No menu in my admin or any reference to this plugin anywhere in my admin (the same for your ACF Frontend Display plugin) NOTHING. Where can I find documentation for these plugins?
I am really interested in making these work.
I also tried your backend trial. Same there, there is NO form builder in your trial either. So what’s the story? How do you run this baby?
Look forward to your DETAILED response, and I mean DETAILED, please!!! Thank you in advanced
