Which site are you talking about? And how are you locked out - is it not possible to log in, but you can see the site, or what? Please be more descriptive about the nature of the problem, 'course that'll make it easier for us to help you. Okay? ;)
I did the upgrade and uploaded and the site is all there, all the pages seem fine and looks fine. I just cant log in using my Username and Password and I cant remeber what Email address i used for it
You can go through the MySQl->PHPAdmin, and check the email there. Look for the table: your-prefix_users, and click on the icon to the left where you can view the table, and see which email is used for the user_id 1. You'll find the prefix used in the config.php, in the root of the site in question!
