Can't buy game

Hi, i have a problem, i have been testing the game, and i wanted to buy it, but when i click the paypal button:
Fatal error: Call to undefined function curl_init() in /home/sites/ on line 75

Is this my problem? or is anything related to paypal, webpage programming issues?

Thank you

Definitely not your problem, I seem to experience this bug as well.

This seems relatively new, as this bug has never been seen before you reported it.

Ahh, looks like we caused this when fixing the “No emails arrive at hotmail addresses” bug that the buy system had this week. Should be fixed now!

Yes indeed it works now.
Happy owner of the supercharged version!
