Paginated comments not working

Hi,
I know this topic isn’t new, but I couldn’t find a solution to my version of it. Actually this is the first time I ever had to post a question about WordPress myself. So there it is:
My script is a slightly modified version of the ThemeShaper project by Ian Stewart. I followed the tutorial, but you can get the updated version at :
https://code.google.com/p/your-wordpress-theme/source/browse/#svn/trunk
I still have a long way to go before my blog can be “released”, but here is a link to my comments test page:

I describe the problems I’m having with the comments on the comments them-self. The main problem being the pagination failing to paginate (its enabled in discussion). I get the nav bar but I get redirected on the first page. I tried several code changes in comments.php but couldn’t figure it out. I’m currently using the updated version of Ian’s comments.php and I checked for the functions, they are all there. What am I missing?
Also, I tried pagination plug-ins, none of them worked, so I deactivated them for now.
Although I thought to have solved the overflow problem in my css, it seems to persist when I respond to child comments. It seems that child comments outgrow their container. Could this be related to the pagination problem?
Any help would be greatly appreciated.

P.S: I’m working with Firefox, and have never tested the layouts on another browser. Sorry if this causes any trouble.
