Problem with access Stats

Hello everyone. I am running Access Stats 1.12 on one of my sites( s-e-racing.com). It has worked great for awhile, then all of a sudden, it stopped. Nothing has changed though. When you click on evaluate, it does nothing. If you look at the source(after clicking evaluate), it is incomplete

I'm not sure what to do, as I don't want to lose all the stats I have.

You can view the script yourself at http://www.s-e-racing.com/cgi-bin/stats/stat.pl

Let me know if you have any ideas. Thanks.
