perhaps you aren't providing enough information. For example, in your other topic you say you are getting a 404 error. Is the domain you uploaded your files to brand-new? Did you just register it? Perhaps you haven't waited long enough for the domain to propagate. This would be easy to test.
The script is really not hard to install, however, if you can spare a whopping ten dollars, the authors will install it for you. I'll do it free if you want, but this would mean you have to trust a stranger with your login details. It's up to you... My guess is that your domain has not yet propagated or you have uploaded your files into the wrong folder on your server...
