So, if settings caused the server to freeze, functional settings and server would be restored to working order automatically.Although it's always recommended doing a backup of hfs.ini file, the whole problem/issue you had (about the freeze), was a very exceptional one. And it would never happen again if you follow what I've posted HERE. Have you read that? You currently have your Private Message disabled on the forum (User 'danny' has blocked your personal message.), so I couldn't let you know about the updated post.
Please keep your PM open...
Cheers,
