Where can I download Air at Alton Towers recreation for NL2?

Hi, I hope I'm posting this in the right section. Apparently there is a good recreation of Air (now called Galactica) at Alton Towers for NL2 somewhere, but the download link is dead. I wonder if someone could upload it here or post a working download link to the full track. It seems a shame for it to just disappear after someone put so much effort into it. Thanks.
