And another update: RWInfo-1.0.5-update.zip. The download is here.
This solves a problem with d:id-Attributes in routes containing extra space characters.
Some additional hints are show if you open the full post.
If a route is not showing up or if there are error messages popping up, you can open logging window through "Window ->Display Logging window". This will show you some more information about the problem. If you click on a message it will show even more details. These can help me in nailing down the problem, so please send such messages to rwinfo at 10a dot ch.
