Problem with the app – Free Tone - Calling & Texting Review

This app was working just fine. But now I've got a problem where I can't make any phone calls. There's no connection at all when I try calling. It's like the system is not recognizing it as a number, because when I finish typing the number in, the “Free number” tag doesn't show up. And for some reason, the Freetone website is down, so I can't go there to find out what's going on. This needs to be fixed ASAP. I don't want to lose my free number because I unable to make phone calls.
