This thread is resolved. Here is a description of the problem and solution.
Problem: The issue here is that the customer wanted to translate their default wordpress texts such as Category, Search Post etc. However the customer had the Multilingual Blog installed.
Solution: In order to translate these texts you will need to install the Wordpress Multilingual CMS and not the Blog version.
