Use this link donwload the admin toolkit. It resloves your problem to access to admin panel and change your admin password and verify your admin email account.
For visual verfication try after this without visual panel if an user can register
After finshed don't forget to delete the install folder
PS: If ou know to use phpmyadmin there is an other way to resolve the problem
PS:Sorry I forgot to add the link in 1.st post
