Okay I managed to open the client by using some .bat and I used the Neuz.exe that's provided on the UPDATE_3.
Although I want to know what is this error on this resource error log:

Also, there's a warning that keeps popping up whenever I open the game and it says "Due to insufficient memory, the quality of the texture will be lowered".
