1. On the page:
http://www.nissan-techinfo.com/infiniti, there is a link entitled "View Subscription Details". Click on that.
2. A new page comes up. Click on the link that says "One Day Subscription". First thing it does is pop-up a page asking you to agree to a license agreement. If you have pop-ups disabled in your browser, you will not see this till you enable it or for that site. Click on "Accept" in that pop-up.
3. The main page will now show a page where you can add a "One Day Subscription" to your cart. Click on that.
4. Takes you to a page where it says "Free Registration" or you can log in on the right side. Entering a valid login takes you to the cart page. You can checkout here, then the forms start clicking through the pages where you can pay for the access, etc.
After that, you will be able to access the files. If you have difficulty, please send me e-mail and I will try to respond promptly.
Enjoy!
