Editor Help

Basically, I keep getting this error message. I've tried to make my own league and this error message pops up when I try to load up a game with the editor file.

Here is the link to the editor file: http://www.mediafire.com/?xe39rxp6o3abeax so if anybody could sort it out and send me back one that will work it will be greatly appreciated.

Thanks.
