yeah this has happened to me many a time, as im on msn and aim quite a lot, there are many times when my list has got deleted, really there's nothing you can do...sometimes the list comes back, sometimes it doesn't, my brother, a computer programmer, said to not use it for a few days and come back and see if it works...i dunno hope that helps, best of luck....its all crappy, though, hotmail gets so much junk mail and viruses...
