Super Paper Mario freezes in world 2-2

Whenever I talk to Mimi in world 2-2 of Super Paper Mario my Wii freezes. Do I have a bad disk, or is it my Wii? (Actually, I can talk to her once, but if I try again, the freeze happens.)


According to Wikipedia:

"PAL copies of the game contain a bug if the language is set to English, German, or Spanish. In Chapter 2-2, the game will freeze if Mario speaks to the character Mimi without first picking up the key. Nintendo of Europe is replacing the game disc for no charge with a version that does not contain the bug."
