Did you create a new database from the template or is the template itself not working ?
Case 1: Database
Did you read the "Using this database" document ?
You have to create an empty database, first. Then copy the language und the config docs from the template to the newly created database. After you have copied the documents, update the design of the database.
Case 2: Template
if you use the database locally, u have to enable uniform access ( konsistente ACL )
let me know ;-)
