After install you get an IndexOutOfBounds exception on AreaDomainLock when accessing language module.
We discovered that the DefaultEmptyData package is not valid against the DefaultEmptyDataSQL package since the update.xml in the Files folder has version number 199 and the database should contain a new field in the Area table named "AreaDomainLock".
We fixed this but entering the number 191 into the update.xml file and restart the webapp the load it, then it updates the table and the language module is accessible again.
But we don't know if there are other issues.
So please update the DefaultEmptyDataSQL package.
Thx
