Hi Supriya
Try looking at the logs. To do this, click "Logs" in the navigation panel, and then in the log panel click ServiceRecent.log. Scroll up to find the latest login attempt and see what messages were shown in the log. If there's not enough detail then you need to increase the logging level. By default the logging level is "Information". To get more detail select "Debug".
If that doesn't help to clarify the problem then you can post the relevant portion of the log here (make sure to remove any confidential data), or e-mail the log (zipped up) to support@enter...
