Question about Google Earth

[tres]

I'm trying to plot a visual route through a few dozen waypoints.

But, i'm struggling. A great deal.

Anyone any ideas?

edit: ignore me, i'm just a retard!

OK, i'm back, I need help.

I managed to get a route from the UK through several European cities - but after Budapest, Google Earth can't seem to find a route anywhere - to Bucharest for example.

Any idea how I can get around this? Or any other method of planning and showing routes through Europe and Asia?
