It seemed to install correctly. However, the description doesn't indicate that advanced features like recurring events require the paid version. If I were buying a calendar program, I would choose something else, since the English in the interface is terrible. I hope the author isn't a native English speaker, otherwise it's inexcusable.
Calendar appears to have lots of functionality in the paid version only. Description on the WP Plugin search is not for the version you can download there. Able to enter a single event only. No reoccuring events.
When I attempted to enter an event I couldn't find out how. No + or "add new" button. Had to just click all over the screen until something came up. If there is something it's not easy to find in the free version.
