Cannot Login

I've never had any problems logging into my smartftp program before. Now after I open my local browser and then attempt to connect a message pops up in the connecting box that says;
SmartFTP v1.5.990.0
Local file '%s' not found.
Cannot login waiting to retry (30s)...
and then it continues to retry. It would be greatly appreciated if either a smartftp user thats encountered this problem before or an smartftp representative that could help me figure this out.

Hi, SmartFTP 1.x is not longer supported, update to the last SmartFTP build.
