Good evening Alan,
looks like a RB software problem. Windows with SQL messages appears on my screen. So I closed the programm and startup again. All problems looks to be solved......
Presumable no problem with the route database at all so it looks like a local problem.
Sorry for any panic I maybe caused, so please ignore my messages before about flights not showing but in the d/b.
