You do not need to register PinPoint. It is included with ACP Expert.

The two registrations you got were (1) the immediate auto-generated one from the Software Store and (2) the one coming from Stephanie's Customer Support system when she enrolls you here for the Comm Center etc. The two licenses may differ due to the date being a day different. The second one from Stephanie's system contains much more detailed info so you can ignore the first one. Just use the second detailed one's info.
