Thank you for your post.
FileMaker Pro comes with two activations. You should still be able to install the second occurrence on the machine. If you run out of activations, you can contact our Customer Assistance department to get another activation. (If you live in North America, the phone number is toll-free 800-325-2747).
I have email for new activation code and still waiting response from customer assistance dpt.
Hope I can get it very soon.
