If you forgot your password please click on the Forgot Password link on the login page.
If you already tried that and it says "Oops, not able to proceed" or some other obscure error, the problem is most likely that you are using a different browser for the link you got in the email message, then you did when initially requesting the reset link. In other words, you requested the link, it arrives in your email, and when you click on it, it starts a brand new browser. That will fail.
Instead, copy link from your email, and then paste it into the same browser window/tab that you used to request the reset link.
