You won't get the 'GO' button either when attempting to navigate a track if the number of track points are more than 10,000.
In Basecamp, you can double click in the map window on any route or track and a property window will open. The 'Summary' field for a track will show the total number of points it contains. On a route it will show the total number of via points it has.
Basecamp is your friend!
