I was having the same problem as Ronson and swgreed. The appropriate tables where not created in the installation so I added them manually with instructions from katon.
First I did an install om build4. When trying to access the front page I got the 404-error. I logged in to phpMyAdmin and changed the following manually.
In the content table, rename columns content_name and menu_text to content_name_en and menu_text_en accordingly. Plus add columns content_name_de and menu_text_de. If you have installed additional languages, add columns for these to ie. for swedish add content_name_se and menu_text_se.
Further, In the htmlblobs table, rename the column html to html_en and add column html_de and if you have additional languages add them here to. That's it.
Thank you katon for the fast answers and support. It's very appreciated!
