I installed this plugin and after going to the page where it asks you if you want to change admin (WHICH I DIDN'T!!!) it simply killed my access to the site, now I get this message: You do not have sufficient permissions to access this page. And I'm the admin!!! Can I simply delete the plugin? I tried to change the wp_ to something else and supposedly it did it, but for what I see on FTP it didn't change any file, however I'm not sure if it changed something in the database. At this point I don't care at all if my files are called wp_ or whatever as long as I get my site back!!
