Fails in Treehouse but runs in IntelliJ

The issue seems to be with the IOException requirement of the BufferedReader. Compiles and runs in IntelliJ but not in the treehouse console.

#  This is essentially what I am testing 
1.  The user is prompted for a new string template (the one with the double underscores in it).

  a. The prompter class has a new method that prompts for the story template, and that method is called.

2.  The user is then prompted for each word that has been double underscored.

   a. The answer is checked to see if it is contained in the censored words.
      User is continually prompted until they enter a valid word

3.  The user is presented with the completed story
