Why did you have to create a new account?
What error do you get when it will not load?
i had issues getting illustrator to work with the adobve cloud and that was the only solution.
error: operation could not be completed, but it works in the old admin account.
When all else fails to fix permission problems a new account is usually the only way to get it to work.
That that familiar with Mac but sounds like what ever permission levels you set for new account was not enough for Bridge.
In the new account try running Apple utility to fix permissons and see if that works.
