FTP Software Error When Setting the Alert Update Time

Hello everyone!
Please help me out with this problem. I have noticed that an FTP uploading facility that I've been using to send some files to a web page via live data suddenly stops in the middle of uploading files whenever the application is not set to update after six (6) seconds.
However, when I tried to set the alert update time for around five or six minutes, the application returns the following error 'Application Error. A generic error occurred in GD+' after uploading files for about 13 hours. This perhaps is the most wonderful software that I've ever used to upload my files online, and because I am only starting to get the hang of it, any help from those who know what to do or those who had experienced similar problems will be very much appreciated.
