Here is a Plugin Bug:

“I figured out the solution…if you remove any of the original roles as defined by the core installation (even if they are not being utilized in any way) it will break the menu option functionality of the plugin. I had deleted the “Editor”, “Author”, “Contributor”, and “Subscriber” roles, leaving only the “Administrator” and my own custom role “Bike Registry User.” By re-creating these roles that I deleted, the plugin works fine.”
I have deleted the default roles since they are not used…and it seems the plugin is not working. ??
Maybe you have done the same?
