Kapitain. Buy another game, save your nerves. I usually simply stop communicating with people like that. I just don't need unneccsary agrevation in my life. If I need to fight with someone - i play some sport.
On second note - you paid 30 quid for it?? I paid $10 in a Wallmart long time ago. :P For someone moving to Switzerland in 5 years, you shouldn't be bothered by J30.
