First Run WorldTennisTracker is installed with initial database containing only tournament headers but without tournament data like matches, etc. Therefore after installing the software you will need to update database. Also newer data (like matches of currently played tournaments) has to be updated from server and sometimes the software will need to be updated too because of new features added or database structure changes. During update you will need Internet connection. After update all data is stored on your PC locally, and you can use the software also without Internet. While your database is in initial state, you will be suggested to update database with the following message:Click "Update" if you would like to proceed with update. You can also perform update later any time.
