Just my 2 cents, for what that is worth.
I would start over. Clear everything then follow this excellent tutorial by our very own Jayhawks659. You can stop at loading The Crew and substitute what you want to load as far as addons. Skins and launchers can cause a lot of grief. Once you have a stable operation you should be able change things around to your liking.
Oh, as Mark suggested in his post above. There might be an issue with overloading the capacity of the Firestick with a build.
