Renaissance Navigator

I purchased a used Renaissance and when I did I got sick and needed open heart surgery and now that I am finally getting around I started looking at it and quickly realized that I need Renaissance Navigator to operate the machine. Can anyone help me? I need to purchase it and don't have any idea where to get it from. I paid $4,000 for the machine and I am unable to use it.My emailis stacyknapp@yahoo.com

I would appreciate any advice that anyone could give me on this. Even if there is another program that I could buy that would do this so I can use the machine.:confused:
