I have reinstalled the plugin many times in Windows with IIS. I have reinstalled and upgraded PHP, MYSQL and WordPress to their latest versions. When running the plugin under using Windows with IIS using FASTCGI with PHP configured, the plugin will not save the questions you enter into the mysql database.
There is also a problem, when you post the [WpProQuiz X] to the front end. The [WpProQuiz x] does not show the "Start Quiz" button on the front end for the user to take the test.
I also have a request. Is it possible when you start the quiz, the user has to first sign in, before taking the test. As it is right now, the user could preview questions without signing in to take the test. By making him sign in first, he will not be able to browse the questions and cheat, when the user does take the exam.
It would also be nice to have an option that only "Registered Users" could take the test. This would stop people from creating a bogus account to preview questions.
Others have requested being able to change the words on the test buttons. In the quiz configuration, it would be nice to have an option to see the different test buttons, and change the text and color of them.
