When TheBetEngine is started it pulls down data concerning today's courses and today's races from a central server. This data contains information about the types of courses (Flat, NH, AW) and detailed information about each race (like Class, Handicap status, etc). TheBetEngine then uses this information in conjunction with your settings to determine which races should be displayed on the Race grid.
If, for whatever reason, you need to reload the race data held by TheBetEngine, then the quickest way to do so is to:
1. Go to Settings/Diagnostics and click on the "Clear Today's Info Files" button.
2. Restart TBE
