Why is it in Korean? Is your windows kanguage set to Korean (i can see RU on your keyboard language switch bar) or did you download the Korean client? The Korean client won't work on EU Cabal you can only use the EU one.
Oh yes, your Korean language pack isn't working properly as the title of that error box is an ANSI or ASCII encoding of Korean text and not Korean
You can download the EU client here if you need it.
i have EU client ))
RU is laguage in icq, or msn D
