I am using windows live mail from a long time ,  I have 3 email accounts on the same, recently I have a problem with my gmail account for which it is asking for password again and again, even after entering correct password ,it is asking the same again. The other two accounts are working fine. when we add another gmail account it also works fine, but with this particular account there is a problem, I repaired the windows essential also but it is not working. 

if anyone can help
