Take a deep look into the EB-FAQ it will answer most of your questions.

This thread gives EB-related advices.

Last but not least I would ask that you look up your build number shown in the main screen. There has to be 1.2 if not you installed the patch wrong.
In that case, follow this guide to install EB right. Keep in mind that 1.2 is not savegame-compatible.
