Error after tranfering jpfChat to other domain

[Woosh! Webdesign]

I developped a website in a subdomain of mij website. When the website was finished I copied the files, folders and MySQL database to e new domain. Everyhting went smoothly, but when I click a menu-item for jpfChat, I get the following eerror:

Fout: 'chat.js.tpl.php' kan niet worden gevonden, controleer het pad naar thema '/home/XXXXX/public_html/praatplek2/components/com_jpfchat/pfc/src/../themes' en uw thema 'msn' is correct

In english:
Error: 'chat.js.tpl.php' could not be found, check the path to thema '/home/XXXXX/public_html/praatplek2/components/com_jpfchat/pfc/src/../themes' and your theme 'msn' is correct

Apparantly the component directs to a file or folder on my subdomain rather than the domain where the problem occurred. Does anyone know how to solve this?

I'm using Joomla! 1.5.12 and jpfChat.

Your help is really appreciated.
