Going to try taking it to the office and see if I can make it work on my laptop. Really really angry with this thing. Feel like I wanna punch Mr. Navionic in the face right now.
If you are trying to use Internet Explorer---DON'T unless you have IE 9 or lower.
Firefox, Chrome are a couple that have no issues with the Navionics web site.
