The manual states:

The HELP section within the game is very useful.

If your game fails to report because of your connection being interrupted or other reason, you can revive the game reporting sequence by opening the RSIBB folder and double clicking on Purebaseball.exe. There is more on this in the FAQ. Once you have reported a game, you will be taken back to your schedule screen and will have to RIGHT click and refresh the frame in which the game schedule is located to bring up the score of the game. Clicking on a reported game will bring up your box score.
