Great explanation for the use of a LAN with different computers and connections. The basics remain the same whether done using networked computer or using two separate computers. You hit the nail on the head....restoring from a backup is the key. The restored file regardless of which computer it is on, is the file which will be synced to the AMT. Even more key is ALWAYS enter the data into the file synced to the AMT. After recovering my data base, I have changed my methodology. Now at the end of the day, I perform a sync with the AMT and then make a backup of my file. Thanks again for your comments.
