I'd suggest overwriting all files except Settings.php with the files from the SMF 2.0.2 large upgrade package. Also, try changing the passwords of your ftp, hosting and mysql accounts, as you might have been hacked. Don't forget to use repair_settings.php, though. Also, are there any other admins or moderators on your forum, apart from yourself?

Wait, are you sure about that? Then it's possible that you might have been hacked, so please check this out: http://wiki.simplemachines.org/smf/Hacking_-_I_think_I_have_been_hacked
