Tabs issue in ADManager 6.1

Tabs issue in ADManager 6.1

After i installed Any Build of 6.1 AD Manager Plus. When restore database from old version, we are not able to open two tabs ADMGMT and Admin. 
In Home Tab i am getting following error :-  [ServletException in:/jsp/dashboard/Dashboard.jsp] LayoutTag: JSONObject["LAYOUT_ID"] not found.'
In Admin Tab :- it is not opening.
Its working fine until unless we restore db from 6.0 .
Hoping a solution.
