This is Downgrade. What a shame!

I had a Ldoce5 detail dictionary app has a lot of features before. Now, after upgrade it is awful. There is nothing!! Where is ldoce5, it was 900 mb. I paid money for it. Ldoce6 is 30 mb. It has no features such as grammer part!! You are cheating? This is not upgrade, this is downgrade!!! Please compensate urgently!!!
