OK. I think I have it.
1. You need to create an "Avid Master Account". Yes, I know we've already created a user/password when we downloaded the software, but this is different.
https://my.avid.com/account/orientat....com%2faccount
2. Link the accounts. Yes, again this is utter silliness to do this, but once created, I saw two other account on the bottom left, and one account (iLok) on the bottom right. iLk was apparently already linked, but I had to click on each account, create/register the same information for both.
THEN it worked.
There software must be good because this registration stuff is awful.
