[SOLVED] Help! I somehow broke my commenting form/comment ability

I upgraded to WP 2.9, and was playing with the idea of setting the comments to automatically close after 120 or 365 days. When I went to check to see if comments were closed on the old posts, they were, but then I checked the newer posts, and those were closed too. I removed the setting to automatically close comments after any time period, but the new posts were still closed. I then went and checked the settings in the new posts and they were marked to allow comments. Next I tried to add a new post, and the comments there were closed even though in the settings for the post they were allowed.

I switched to the default WP theme and everything worked fine, but when I switched back to Atahualpa it was broken again. What did I do, and how do I fix it??

Thanks in advance.
