Mind disclosing what version of 1.9?
Does your 'normal' account have admin access levels?
Are there other users who have admin access rights? Is it possible someone edited your account or a role?
After logging on, use the URL line to go to:
http://yourmoodle/admin/user.php
IF you are able to get there, set search for advanced and in the resulting form set system role to Administrator. The true 'admin' account is the one that has no 'edit' link.
