1. How do I add another language to the list - I need to add two?
If you will look in the documentation under the following link you will see a screen shot and a description on how to add a language under "Creating a New Project"
UI Layer -> Messaging and Locazliation -> Overview
2. How do I get the messages in the database for the application. When I select the add localization option, an empty table called messages, with no fields, is inserted.
Are you referring to the DDT when you say "Add Localization" option? If so, I have attached a .pkg file that contains the structures in case there is an issue with you package file for some reason. Copy this file to the following location:
c:\program files\common files\microfour\strataframe
Just override the existing file (strataframemessaging.pkg). As for importing your localization messages themselves, there is a new wizard that exists in the 1.5 release that will be available by the end of the day on Friday. Basically it just creates the Deployment Data packages for you. You can do this yourself now by manually setting up the Deployment Packages to pull the messages from the MessagesItems and MessageLanguages tables.
