While I appreciate your interest and it is flattering, I would like to know why you don't just copy the content and create your own presentation. As you can see the presentation does not really show as it should here and therefore you would be better off with your own. You don't need permission to copy the content - it is freely available online. Should you find difficulty don't hesitate to ask for help though - and if you still wish to download the presentation I will make it available for you.
