If are getting many errors through the program, try running the Database Repair function found on the Utilities menu. A database repair is not needed each time there is an error unless the errors seem to take a ‘domino’ effect to the system.
Before doing a repair, try exiting out of Horse Show for Windows and going back in. If this does not seem to help, run the database repair.
Rebooting your computer may also help. It may clear up memory issues that may be causing the program to function poorly.
