I wanted to login in my NCsoft account but when I click in the "login" link, my explorer (chrome) says me that the site is NOT secure and that I shouldn't enter, specially if I didn't get that warning before.
What should I do? Is this happening to anyone else?

i think you find that a lot of sites will always come up as non secure even if they are .. its something to do with with their certificates and not every site can be bothered to set all of its certificates.

NCSoft? Insecure? Never! 
Just be VERY GLAD Anet asks for your char name to login as well.

The issue you will find is that their certificate has expired and they haven't updated the certificate. Unfortunately this does happen with a lot of sites.. where it can take anywhere from hours, days or even weeks for the site/company to update their certificate to a current one.
