This plugin is just ridiccolous

I’ve installing this plugin, but after I installed it to my multisite, i’ve tested it in my network and this plugin made me frustraded because It’s very difficult to set up, the settings of this plugin appearing only in the multisite network admin page and general settings are not appearing in the main multinetwork settings menu as like instruction in your webpage says. I dont even have lots of plugins, which make conflict of this plugin, because i see other functionalities “language manager”. Actually thats all what I found.
And next, after I figured out how to set up the plugin, I didnt found any possibility choose more then one language for my site. When i went to edit for my site, there was under “relations” only one language, which i chosed first, and dont have any ideas how and where to set up the second language. Just showing me under the “relations” one language and that’s all. When I connected relations with other sites, it was still appeared one language, which doesnt make me sense at all. And there is also no guide how it works properly. So the resolution is this plugin just make me a big confuse and waste my time. I been so hopeful since I found this plugin and desired to extend it to the pro version but if I even cant set up it in the free version, then there is a not point to use this plugin anymore.
