no access to dashboard

I really hope you can help me:
A few years ago I created a blog:
I need to make changes to my contact details as well as redirecting the site to my new website. When I click on "My Sites" (from within the editright page) the message "you currently do not have any sites" appears. when I press on the account button the name that comes up is academicedit (a name I used in the past not sure for what).
How can I access my site and account?
