If your file format only contains these 3 lines, this should work.

  void Load()
  {
      using (TextReader rdr = File.OpenText("savegame.txt"))
      {
          int lineIndex = 0;
          string line;
          while ((line = rdr.ReadLine()) != null)
          {
              if (lineIndex == 0)
                 moneyo = Int.Parse(line);
              else if(lineIndex == 1)
                 workedhrs = Int.Parse(line);
              lineIndex++;
          }
          rdr.Close();
      }
  }

In your code, the lineIndex++ is only done if lineIndex == 1. So you probably parse the first two lines with the first "if" and write in the moneyo variable twice. Then you parse the third line, it's not a number and the code crashes. Put the lineIndex after the "else if" block and it should work as expected.

... I should have used curly braces with the if else if blocks to make it more clear.
