From what I got from your post, it sounds like you created a new windows account, registered it with FAM, then opened Freelancer.
If I was right, you need to make a new user account, open Freelancer first to create an ID, and then register it with FAM.
I presume FAM was picking up your other account ID that you use now, then using it when you opened Freelancer on the new account, so it came up with the same ID.
