Thank you all for taking time to explain it to me. I am installing JDK, Docs, and JCreator at the moment I am typing this. I hope it works this time. Really, I am a computer guy, too, but it looks like I have to rethink that if I still should go for CS! I don't know if it is really complex installation or I am myself ridiculous not to get it installed. Well, I am still working on it. Hope it works. I will keep you guys posted.
