Tenvi error when click game start

I keep getting this error.
When I start the game (I already installed), a patcher/updater will come out and close by itself,
and give me this error

How to fix this?

Don't call me noob or whatever, I'm just new to Korean games as I only play english games.
I have Korean Unicode on, what else do I need and how to get them?

I use both these websites to start the game

http://pmang.sayclub.com/tenvi/tenvi_home.nwz
This site I use my own account (registered with KSSN).

and this site, with a trial account (registered without KSSN).
http://pmang.sayclub.com/tenvi/event/20071227/index.nwz

Both give me the same errors :(

Edit :
I already tried restart, but didn't work.

If can't be solved, then I just wasted my time making account and downloading the game.
