First off make a backup of all your files. Just copy them into same directory call them something like admin-menu.php.backup etc. Then best thing I can suggest is just to hack at it, delete a few lines here and there and see what happens? Is there a user-profle.php file or something similar? Renaming this file will cause same effect as delete.
Like call it user-profle.php2 – should stop them getting there – but it will be messy and your users may *most likly* get error messages..
This is obviously only a temp solution…
