HELP - upgraded FTP and now cannot login

I have just downloaded and upgraded version of SmartFTP and now I cannot send my files away. HELP HELP HELP Why cant I login. I think I have installed over the previous version and I have restarted the computer to no avail.

Hi, plz send a log of the login sesion.

Well, sorry to cause you guys such fuss, but I was in a huge dilema. All ok now. Was not the programs fault. Apparently the recipient I was trying to send the information to had changed my login and password details and hadn't advise me.
