If you want to return to the local database, you should do the following:
1. Go to the File menu and click on Return To Local Data option. If another database is open then all open items will be closed. If some of them are changed then you will be asked to save them or you will lose those changes.
The local data is located in the AMF Daily Planner and PIM folder on your computer (the folder where you have installed the application) and it is called amf.mdb.
