1.7 Trouble configuring Gallery Sliders Everywhere

[Christa_cross]

Hello.  Today I purchased the module Gallery Sliders Everywhere 1.8.5 (v1.8.5-galslidereverywhere).  I am developing with Prestashop 1.7.4.2 (prestashop_1.7.4.2).  I believe I have purchased the correct version of the module.  However I am having a hard time configuring it.  I have found a tutorial named, "Slider Everywhere 1.2 - slide builder demo by Zdeno Kuzmany but the navigation is so different from what I have I cannot follow it.  I will continue to search for information on how to install my version but if anyone could point me in the right direction I'd greatly appreciate it.

PS. I've tried to follow the directions in the module itself but my galleries are not showing up.

Thank you.
