Hi, 
I downloaded the version 10.7.28 and upgraded from 10.7.20. If i now open any of my old race notes and try to run routing I get following error: invalid start position - covered by race note(s). Even when the nearest race note is tens of miles away from route start point. Only completely empty race notes works correctly with routing. Same issue if I make  a new race note file and add one race note to it.
