Mac OSX leopard language problems

[N.O.C.A.]

One of my classmates have a problem with the language on his 13" MBP (2.26 Ghz).

After his "friend" changed the language on his mbp from danish to english, the "international" menu in system preferences is completely blank, with no options at all.

And so i was wondering if there might be any solution besides formatting and reinstalling.

Perhaps a command in the console?


Regards,

Nicolai


EDIT: he's using Leopard
