Must be the proverbial gremlins at work. I get nothing but error messages trying to open Legacy Kline.
Something akin to this is called the "Paulli Effect" after the well known (in European physics academics circles) Austrian physicist, Wolfgang Pauli. Any time an inexplicable glitch occurs it can be blamed on this effect. He was actually celebrated for influencing experiments in a negative way just by his presence at any time in a laboratory setting. It's a funny story and worth looking at.
