I recently added the new Manchester Untied 04-06 kit into Fifa 2004 but ever since, team management doesn't work on the career mode (where u see the ticket for the next match). Whenever i click on team management on the career mode main screen, the game shuts down. It works in-game and everywhere else. On the main fifa screen if i go onto team management and pick a side, it works for every single team apart from Manchester United. Why does it do this? Do i have to uninstall and install again? if i do, how can i keep the saved games?

If you uninstall the game the saved files will not be deleted, because they are placed in another folder (My documents/FIFA 2004/user).

But you could try to run fatGUI first, it migth help.
