guestbook stops generating new html

My guestbook suddenly doesn't know how to jump to a new page. It has happened for some time and the guestbook page gets distored (including the skin I've made, and the header & table) now. It holds over 2000 post on same page!

Reference: http://www.mmp.com.hk/gbook/guestbook.html

I've checked the page_id.txt file, the post id series seems to have jumbled up with the htmls. It doesn't know how to generate new HTML after page 317. Does any body know what is happening? Is there a limit to the maximum post a proxy2 guestbook could hold?

I try to fix the problem in dreamweaver but doesn't work so i revert.

Please help. Thanks!

Can anyone give me a helping hand on what to do?
Thanks!

I'll peruse the code if I get chance or maybe Amber could help as I've never used version 1.5.

Carbonize,
Thanks.
I was thinking of removing the last page (guestbook.html), edit the page_id.txt, and see if it runs normal again.. Hope this would work out. If you / Amber have any suggestions on how to go about this problem, let me know. I don't want to get a new guestbook as old post will be hard to search.

Can you open guestbook.pl and confirm it still says
