Where in the world do you live that you do not have a Brother dealer? There is a dealer locator at the Brother website.
Refer to the maintenance section of the manual to be sure the bobbin case did not moved when the needle jammed. You will have to remove the needle plate to remove the bobbin case. Make sure the needle is at it's highest position when replacing the bobbin case.
If that does not help, then I would take the EM to any dealer that does sewing machine repair - the timing may need adjusting.
