It looks like a Windows Update froze the data server this morning - probably some time around 08:00 - and this will have prevented Course Data from being downloaded if you started up TBE after that time.
The server has now been rebooted (as of 10:25) and things should be back to normal.
If you are affected, then TBE will be showing a red CD indicator in the status bar. If the CD indicator is present, please restart TBE so it can reload the course data for today.
Apologies for the inconvenience.
