I ran the generator, ran FAM clicked on "import from file" imported from the location where I'd saved the adf file, opened up FAM and it had like 30 accounts that just say "new freelancer account".
Thought I would manually add my current account just incase, and now it seems I have 2 account id's that when activated both have the characters from the original account.
Activated one of the "new freelancer account" ones and all was good with that one.
I'm just not sure why there're loads of them.
