Route guide problems

I'm having problems with the Navigation routes on the Gainsborough Phase 2 Map. At first it seemed to work, I chose my bus and then a route and it loaded the red line route path. Now I can't get it to work, I'm using the same bus on the same route and it doesn't switch to show the red line when I select the route. The map has loaded in ok and I can see all the stops and my pointer moves around the map, just no red guide. It works on other maps almost instantly but on Gainsborough I've only got it to work one or two times. Please help.

No worries, I seem to have fixed the problem by simply reinstalling the Gainsborough Phase 2 map. Maybe something copied over something from a newer installed map who knows. In any case it's working now so I'm happy. Thanks anyway.
