Archive not actually Archiving [Solved]

[Chickpea]

Hey guys,

Ok, so I'm at the end of building my site, and everything seems to be working fine except for the archive.
When i click on a previous comic (there are 2 in total so far) i get:

Not Found
The requested URL /d/20081120.html was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

I have a calender on my archive page, i've updated my comic several times, and I'm at a loss as to what could be wrong.
Is there anything i can do to fix it?

Thanks

*edit*
http://chickpea.comicgenesis.com/ is the comic

*2nd Edit*
Well after many hours of leaving the codes alone, i realized I'd left out the l in html for the dailytemplate. Bugger.

Yep, our servers run BSD, so it's the *.html endings for the templates.
