Translation of Prostituierte

I need to write you one more sentence. This is what my teacher told me and the German language is so difficult. So please, as a last favor, would you please write the sentence for me in German?
Our link book file suddenly disappeared overnight, and the technical team had no idea why. We fixed the problem now. Please go to vocabulix and than press the menu Link Book. Do you see it now?
I will start working on it next week. You can also have a look at our site and give me some feedbacks. You know Spanish better than I do. so please be patient with our questions. I would really like to help.
