Thanks for using JustAnswer. This is Leela and I will help you with the question today.
Once you can login to your facebook account, you should be able to view ALL YOUR contacts without any problem.
Your contacts information doesnt depend on your password. As you seem to have already changed the password, the OLD Password ***** work now and it is not needed to see your contacts.
You can REQUEST for PHONE CALL SUPPORT from under Additional Services and I will call you and we can work on the problem via phone.
