I was playing with the language file and I deleted them while the language was still set as a default.

This is what I get now if I try to go to my admin panel:

Warning: main(includes/languages/croatian.php) [function.main]: failed to open stream: No such file or directory in /home/viktorst/public_html/admin/includes/init_includes/init_languages.php on line 31

Fatal error: main() [function.require]: Failed opening required 'includes/languages/croatian.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/viktorst/public_html/admin/includes/init_includes/init_languages.php on line 31

What can I do put it back to normal?

Thanks
