you need to ftp into the folder and check the directories permissions (chmod). Sounds as though they are set incorrectly
either that or go in and delete or rename the delete-duplicate-posts.php plugin. wp will just disable it when it cant find it. If you just rename it, you can always change it back if wordpress gets broken even more.
