Winscp Login error message - Access Denied

Hi
I could run this software till last Friday. But when I tried it today, it is giving me this error message. I used the same
Host name, User name and the password. So there is nothing wrong with those info.
Why I am getting this error message.
Details error message :
access denied
Authenticating with pre-entered password

I uninstall it and instal winscp again and tried it. But could not get a solution.Can you please help on this.

thank you very much
