I signed up for the Salesforce Developer Edition and received an email with a link to activate it. Instead of getting a page enter my password, it instead directs me to the login page. I tried to reset the password and I receive a link by email, but clicking on the link displays a message that the link has expired after 24 hours or has already been used.

Any suggestions on how I can activate the account?
