You didn't get an email? Strange. The emails should be sent. I'll ask our webmaster to check.
Shouldn't I be able to store 10 different addresses? In other words, if I had ten computers, shouldn't I be able to store all ten addresses on all ten computers, or can I only store one address per computer, because that would make a total of ten addresses?
Regardless of whether your address book records point to the same or different computers, the free license only allows you to have no more than 10 records in your address book. Or across all your books, if you have multiple address books created in the Viewer.
