I really liked Crysalis. I wish it were a little longer, but I trust the authors choice. I tried to play Knight Blade but I get I'm missing rgss103e. Darn. I was wanting to play more. lol. Well, Good going on crysalis and if anyone knows where to get rgss103e, take few minutes to reply. good day everyone!
Try installing the XP trial and see if that helps
