getting fatal error

Hi, first of all I just loved this plugin. but while activating and trying to use it, I got this fatal error on my websete hosted on wamp

This is the error

FATAL ERROR: CALL TO UNDEFINED FUNCTION CURL_INIT() IN C:\WAMP\WWW\SUBDOMAINS\TRIAL\WP-CONTENT\PLUGINS\MASHSHARER\CLASS.MASHSHARER.PHP ON LINE 43

Can you help me understand this and possible fix this?

Many thanks
