1. What method are you using to generate navigation routes with BRouter?
2. Have you got "from" and "to" Quick Points working with BRouter? If not, the most likely error is in not setting the additional maptools directory correctly in storageconfig.txt and not creating a brouter.redirect file. See my comments a few posts previously.
3. If you have "from" and "to" Quick Points working, I can only guess that you have set the nogo Quick Point up incorrectly. Could you attach a screenshot of the details of the nogo Quick Point?
