Issues After Datavase Restore

[AmericanPsych0]

I took a database backup from, say, a month ago and restored it on my server. When I go to the forum index page the forums is closed as it was when I made the backup with the same message showing up just fine, though the header image isn't there. (This is the default vB theme.) Well, when I append the admincp/ URL to it, I don't get the regular login I'm expecting, but rather this:

Could not find phrase 'security_alert_x_still_exists'.

I tried searching for 'security_alert_x_still_exists' through a few files and the database dump, but didn't get anything. So what is it? How do I fix it?

The forum's at almost the same domain it was at before, also.

Well that means theres a phrase missing, more importantly, install.php is in the install directorty.

After you have removed install.php, upload tools.php and use its functions to restore the language table.

After that is done remove tools.php from your admincp directory
(tools.php can be found in the do_not_upload directory)

I deleted install.php and I can sign in now, but I'll run tools.php, anyway. Thanks.
