Hello, bother Yun!
I`am sorry for writing back to you late. I hope that I have right answers for your questions. You can use your previous login number and E-mail address and NJWIN doesn`t have a key input system; it`s just for viewing so the best way that you can take is changing OS. If that`s impossible, buy or download Hanme Hangul. Whenever you need help, let me know, and I want to know your fax number, too.
Peace in Chirst!
