Developer Toolkit 1.04 download problem

I’m trying to download Developer Toolkit 1.04 though the Partner source UK site, but when I right click on the link that tries to connect me to the Great Plains FTP site, I receive an error saying Internet Explorer cannot download from the site. Any suggestions where else I can get the toolkit from. If its any help, the url on the partnersource site is{06047C26-E54A-4DD9-B004-018A6A205C3A}&NRCACHEHINT=Guest
