Create new Windows user. Switch to your newly created user and launch the game.. than start the FLAM on the new user and save the new account.. Than you may go back to your original Windows user and refresh the FLAM on it.. You will have 2 accounts
You do not need to keep the "New Windows User" after you done.. you may delete it.
don't get overexcited and make too many characters though. then you'll be like me and need to delete characters and not have the heart to tell your faction leaders.
