Cant pass to step 6 "configuration" when installing

Hi, I am new in shopware, trying to install and give it a try!
When I reach step 5 Installation, it start creating the tables with no problem, but after finishing this step to start the configuration one, it kinds of goes back just as if I never created the database. The database is created and populated anyway. If I enter the database info again it tells "The selected database already contains data. Please select an empty database or create a new one from scratch. " so seem it wont pass step 5 to 6.

What could I have done wrong?

Thanks
