UI Installation not working? :/

People are telling me that the KGPanel.lua file is corrupted. Someone said "I start up wow with the 37 kb kgPanels.lua file and all the correct images in the customs folder and there are NO layouts in game then when you log out the kgPanels.lua is only 1 kb."

I even tried giving them a new one so I assume it might be the file itself that doesn't want to work. I have no idea, though. Could someone give me an insight as to why this is not working?
