languages and custom text for Password Protect Selected Content

With the protection a text apars to insert a password to get access.

First; I am dutch
Second: In every languages I want to be able the give a custum text for that.
Third: I like to be able to get this info before I pay!! I had to pay before I could see this; but I had the question before I paid already.

By the way; I don't like the way your company wants a dashboard on my site and gives a front with answers etc; it's to much on the forground and to commercial; I don't like the idea withoud the standard alternative.
You want to be payed before answer and info; I rather think twice before i chose a plugin by such a company.
