I took a look at your site, and I believe what you need to do is move all your English pages where they are under:
http://www.english.minedition.com/
rather than having them under:
http://www.minedition.com/english
Similarly, you would want to do the same thing for the German pages. What phpDig is looking for is pages underneath the high level domain name for each of these. It isn't finding any, which is why hardly anything is getting indexed.
