新介面不能使用

安裝了新介面   開啟程式會跑出如下:
OpenKore version what-will-become-2.1
@ai_seq = sitAuto route
Network state = 5
Network handler = Network::DirectConnection
SVN revision: 7601
No loaded plugins.

Error message:
Illegal division by zero at src/Interface/Wx/Window/Map.pm line 641.

Stack trace:

在這一行當掉:
          return (
*                 int (($x + $self->{view}{x}) / $self->{view}{xscale}),
                  int ($self->{field}{height} - ($y + $self->{view}{y}) / $self->{view}{yscale}),

只要沒開地圖就可以用
一打開地圖就會當掉
是什麼原因呢???
