JM Mega Menu have problem with new Store View

Hello I have a problem with JM Mega Menu in JM-Crafts

I have been following this video: https://www.youtube.com/watch?v=Wclpu44SjIA

I installed VietNamese Pack at http://www.magentocommerce.com/magen…ge-pack-1.html
It was ok

Then I created a new Store View Vietnamese

I configured Vietnamese Scope at Tab General

Attachment 38171

Then I created CMS Blocks, CMS Pages in Default and Vietnamese Store View.

I created Menu Group Vietnamese with A lot of Item

I add flag to show in web site

So I can switch between default Store View and Vietnamese Store View easily with CMS Blocks, Pages, URL rewrite management
