Translation of fünfhundertzwei in German-English

I am asking you to give me a reply as soon as possible so that we can proceed. Have you ever tested the new version? Many users are waiting for it, and are sending me lots of emails about it.
Therefore we use only the Vocabulix dictionary in our class. It has good features and a large vocabulary base. I will have to send you a few sentences for rewriting if that is OK with you, because the whole is mixed up.
Do you like Hamburg? I've never been there. Maybe I can visit it one day. I hope to hear from you and please write me in German, so that you will also learn it. Do not worry about mistakes.
