Make sure you have the latest tessdata file from Google code

http://code.google.com/p/tesseract-ocr/downloads/list

This will provide you with a list of tessdata files that you need to download and include in your app if you haven't already. In your case you will need tesseract-ocr-3.02.eng.tar.gz as you are looking for the English language files

The following article will show you where you need to install it. I read through this tutorial when I built my first Tesseract project and found it really useful
