Problems reinstalling SDL Trados 2019

After reinstall the SDL Trados 2019, It doesn't ask me to introduce again the licence and I don't know why. In fact, when I go to the website where it is the license code it says that it is not in use. I had to reinstall it because when I create a new project or I work with a sample project, the languages which I have chosen, they doesn't appear, how can I do to reinstall everything from the beginning introducing the license code?
