It is a new track! This is the full length version of Isle of Man (37.728 miles). The abridged/shorten version you have installed in your IofMan track folder only had 15.388 miles.
Just download the full or lite AAIOM v1.1 of the homepage http://jrpearson.hom...MMCRelease.html
and use the installer that comes with the track.
It will then create a new folder in your GPL tracks folder named AAIOM.
Edit: ginetto you were quicker.
