"Login failed" in Web Intelligence Rich Client

Hi Experts,

I've got error message "Login failed" when I try to login to Web Intelligence Rich Client. I used to be able login to Web Intelligence Rich Client a month ago but now I can't login. Not all my colleagues have this problem. I can access on other machines without any problem. And I can use Web Intelligence in BI Lunch pad normally also.

I tried to uninstall and install Web Intelligence Rich Client back, but it still raise error message.

Thank you,

Sopharo
