after upgrading archives don’t work

Hi, I recently upgraded from .72 to 1.02 and it seems my archives aren’t archiving any of the posts since the upgrade (my old archived posts still list correctly.)
Here is an example of my archiving code:
<. ?php if ($posts) { foreach ($posts as $post) { start_wp(); ?>
<. ?php get_archives(‘postbypost’,”100″,2,””,”- “,”
“); ?>
< !–
<. ?php trackback_rdf(); ?>
— >
<. ?php } } // end foreach, end if any posts ?>
I added a “catid” variable passed into the get_archives function and accounted for that in the function as well. I don’t think this is the problem, as my older posts are still archived correctly. Has anything else changed that I need to do in order to get my new posts to archive? Thanks in advance.
