I'vd done the game every day for the past week and (other than not winning) I've had no problems with the software. I know that I haven't gotten the same numbers each time, though I can't say for sure if they've been unique every single day.
Really can't believe the whining in this thread.
If you don't like WN, don't play.
If you don't like ePrize, don't play.
If you can't make it work on your computer, don't play.
If it is really causing you so much stress that you have to post repeatedly about it, don't play.
