Guestbook errors - PLEASE HELP!

I've managed to make a few problems here.

First I was getting errors in the Guestbook Admin:
Warning: Cannot modify header information - headers already sent by (output started at /home/jason/public_html/comments/lang/english.php:104) in /home/jason/public_html/comments/lib/admin.class.php on line 33

Warning: Cannot modify header information - headers already sent by (output started at /home/jason/public_html/comments/lang/english.php:104) in /home/jason/public_html/comments/lib/admin.class.php on line 36

also, I was getting a similar error when I try to 'Add a Comment' to an entry. With headers already sent by:
lib/comment.class.php on line 152

The post still worked, but you got an ugly error. Others have had this problem and I tried looking for the fix mentioned on this forum, but I can't find any extra text before or after the <php> tags on my page.

So I tried re-uploading the pages that it said were responsible for the errors:
admin.class.php
comment.class.php

This was the stupid thing I think. And I failed to keep the original files.

Now I get a new error and the post does not work. Also I no longer can access the Easy Administration page. I get the same error:
