The problem is simple: I can't choose Mario Circuit. At all. It freezes every time. Not using any modifications of Brawl. I USED to use BBrawl but have since removed it. Why is this happening?

EDIT: I should probably clarify: This happens with AND without BBrawl.

So I dumped some portraits into an unedited sc_selcharacter_en.pac. I removed the _en, and placed it in pf/menu2. When I reach the CSS, it freezes as soon as my cursor goes over a character, regardless of whether or not they have a custom portrait applied to them. Help?
