Free for all links help

Hi

I installed the ffal script and it worked great, then my server moved my site to a new ip address so....... now it don't work anymore. I have done everything including putting the new address in links.pl and links/addlink.html. It still views when I use the old url but won't view any new posts. When I emailed my server they said use the new url, but then I get a page that says Error.

Any ideas?

Thankyou
