Exporting SprintTimer Schedule
In RaceManager go to Settings > Timing System in the menu.
Usually SprintTimer will be set up as the Backup System
Check that the Backup Path is correct, and points to the computer with Sprint Timer on it.
This will export a file called SprintTimer Schedule.TSV to the Backup Path you specified above.
In SprintTimer go to File > Settings in the menu
The Schedule File should be pointing to the same file you exported from RaceManager.
Scroll down to the last race in the list and confirm the event name is as expected, just to make sure you have the correct schedule file.
