NOT WORKING

I just purchased SMARTFTP after using it for quite some time. I purchased because I was unable to connect. I'm still unable to connect. Never have had a problem before. Why now. I just get my little hourglass that means busy. like it is still connecting.. well that has gone on for over 3 or 4 hrs now.. still won't connect. Please help me connect ASAP. I hope I made the right purchase!@!!!!
