error editing example templates

Hi,
I have used your joomlamailer with success on my live site but now using it on a site I am building on xampp that will go live soon and when I go to edit one of your existing templates it gives me this error:
Fatal error: Call to undefined function curl_init() in C:\xampp\htdocs\InfiniteAdmin\administrator\components\com_joomailermailchimpintegration\models\templates.php on line 35

can you give me a way to fix this please?
In gratitude
Michelle
joomlamailer version: 1.7
Joomla! version:1.5.21
PHP version:5.3.1
MySQL version: 5.1.41

You have to enable the curl library in the php.ini of xampp.

Thanks heaps for that.
for anyone as new as me to this instructions on how do to that can be found at www.tildemark.com/programming/php/enable...p-on-windows-xp.html

Much gratitude
