I get "Host not found" error message when try to publish photo gallery maker to FTP

Q: I downloaded free version of your VisualLightBox. It generates beautiful picture galleries that work great locally. But I have problems when try to publish my gallery to FTP. I enter the FTP information to publish Visual Light Box gallery and it tests OK. When I attempt to actually publish it, I can't connect to my server. I get "Host not found" error message.
Please help me.

A: Check that you selected the created location from the list of available locations till you
press Publish button.
