Error When Clicking The Login Button In The Ui

When I am trying to login to my bitdefender, I am getting the error message. (pls check the attachment).


Earlier, I was able to install Bitdefender free edition correctly from my admin account in my desktop computer.


The internet is also running perfectly in my machine.


So I am unable to understand why I am getting the error message? (see encircled section in the image).


I think that though my Anti virus is installed, but it is not working.


My OS is WinXP (SP3)


Do I need to enable any service in my Windows desktop?


Thanks,
