Hi,
After a few hickups , I ran BleachBit , cleared everything.
rebooted the system. And also DNS.
Then I log in again, clicked remember me checkbox. :) And it worked. Now Its not kicking my @$$ as of now :)
But earlier it didnt work to be honest. May be II is flagged in my country or my ISP didn't like it much :D but as of now the problem seems solved. :)
Cheers and thanks everyone for heads up..
