The reason why the offline use of the Sports Monitor might not be working, is that the program has been used in offline for too long. The Sports Monitor can be used in offline for a maximum time of 30 days. After that an online login is required in order to continue using. The reason why there is the 30-day limit is that the synchronisation might get stuck if there is too much data coming through all at once. Also the limit is there to prevent any misuse of the software.
After logging in with the Internet connection the Sports Monitor can be used in offline again for another 30 days.
