SmartFTP is not working properly

Hi All ,

I have downloaded the latest version from ur site, tried to install, and it works but for only one day.. When i tried to start the program 2nd time it gives me the warning that mytrial has expired. Although the program is working (somewhat) i could not able to open 2 diferent FTP sites. When i check the about tab, it shows me days of use 1442. Please help...
