I've checked this application, but it doesn't appear to be available anymore. There is no website to acquire the software or at least some information related to its license type, download possibility or something related to these procedures. It's also possible that the software was discontinued from development making it impossible to buy the software again.
I recommend using Amazon to look for a dictionary since there are many available. Visit the website for your language and then type German-English dictionary and multiple offers will be shown on screen.
