Problems editing in bikeroutetoaster

Does anyone know how to edit an existing map in www.bikeroutetoaster.com , I created the map a few days ago and need to tweak it. I am able to move the course points but the new route doesn’t follow the road. I have tried autorouting on and off and various changes to the settings but the new points won’t follow the road. We have a 112 charity ride to complete on Saturday 24 April and it is driving me mad. Any assistance will be gratefully received.

You can print it out or use:
GPS Exchange Format
Garmin
TomTom
Google Earth
Geolives
Geolives iPhone application
It'd be nice if RouteYou.com let export .tcx files otherwise I'd give that a go.
Is there a mapping site that lets you edit your route easily?
