Curl error on licence activation

Hi,

I just purchase awoCoupon pro version and I'm not able to activate the licence.
When I click on activate in my admin section (components->awoCoupon->Licence), I get following message :

Fatal error: Call to undefined function: curl_setopt_array() in /homez.406/myslimmi/www/administrator/components/com_awocoupon/models/license.php on line 7

What can be the reason ?

Regards,

hello, php 5 is required for that function to exist. Please send me a private message with your website and I can manually activate it for you.
