mylesdragon67 on "Email Before Download Plugin cURL problem"

Hi, I am having difficulty with the plugin. It worked ok until a week ago!? Now (in the settings page) when i click the link (section 2) "check if cURL is enabled" I get an Internal Server Error on the Site. I have checked everything and reinstalled the plugin etc but still the same problem.
I have a duplicate of the site elsewhere and it is fine.?
Can anyone help please.
