Connection issues

Its strange but yesterday I downloaded the client from this site and I connected successfully, but now once I logged out, every time I try to connect it fails, checked the logs and it says the following -

1/31 20:38:39.541 GRUNT: state: LOGIN_STATE_FAILED result: LOGIN_SERVER_DOWN
1/31 20:38:39.541 GRUNT: state: LOGIN_STATE_FAILED result: LOGIN_FAILED

People are playing ever since so its obviously something locally here, can you help me trace the problem.
This is the client with wod models.

Downloaded old models client and have no problems now.
