Not sending SMS, redirects to missing website

Hi,

I just installed the SMS for Jetpack but when I click on the “SendtoSMS” from the share bar all I get is a new windows that sends me to sendtosms.com and then redirects to a “Sorry, the page you were looking for does not exist or is not available” and obviously no sms is sent since no phone number was even entered…

Can you please help me here?

Thanks,

-Daniel
