    No instances for (Read (IO String), Num (IO String))
      arising from a use of `get'
    Possible fix:
      add instance declarations for (Read (IO String), Num (IO String))
    In the second argument of `($)', namely `get cp "" "password"'
    In a stmt of a 'do' expression:
        password <- forceEither $ get cp "" "password"
    In the expression:
      do { config <- readfile emptyCP fileLoc;
           let cp = forceEither config;
           username <- forceEither $ get cp "" "username";
           password <- forceEither $ get cp "" "password";
           .... }
