It sounds like you're using LWP::Simple inside a CGI script. We need to do some simple information gathering before we will be able to help you at all: Are you getting an error message? If so, what is the error message? You may need to examine the server's error logs (or use CGI::Carp 'fatalsToBrowser'). Is your script even compiling? Perhaps you do not have this module on the new machine?

It could be any number of things with the vague "it isn't working" description and nothing in the way of error messages or behavior descriptions.
