This is the error I get when I try to load her. I'm using Mugen 1.1, and my screenpack is Mugen AX2 with the Ultra Big setting for the character select.
 
Error detected.

It also gives the 'character is older than this version of mugen' error as well. The MugenVersion in the DEF is listed as 04,14,2002.
