On the other hand, do whatever you have fun doing. My friend plays on peaceful because he doesn't want to be distracted from building cool stuff by annoyances like staying alive and avoiding monsters. I think that's part of the fun, he doesn't. It's all good.
hmm odd, that worked for me, are you on windows or linux? I don't know if it looks for the same properties file on windows (only got a simple linux server running here)
