I can get logged in through the link in the mail I got but if I try to change password through my profile I obviously can't remember my old one and using the "new passsword" that I got in the mail as the old one on change password page doesn't work either....

How do I do it?

just logout, then try to log in and click on "forgotten password";

You'll receive a mail with a new password.
Login with the new, and go to your profile to change it.

Ps: I don't have access to your password.
