Wodrpress Plugin Not Workding

I am a paid member with Envato Elements / Placeit.net. I had downloaded this wordpress - WP Lead Capturing Pages , but when I installed it, it says no plugin is found. Is Envato Element support can assist to look into this? Any possible to contact the developer - kamleshyadav so that he can fix this or can Envato Support assist to fix this? I believe this is a good plugin to use. Can anyone please assist?
