If anyone who has the same URGENT problem as the original post:
this is a korean web hard + document editing tool that converts .hwp file to .doc, .pdf, .text, .html ect. and vice versa.
(www.naver.com is the most popular Korean search engine)
however you must login or use a temporal access to use the program (free of charge)
but you'll need to know korean. Grab any korean nearby and ask for a short help.
