I wanted to change it - but after clicking on it (button with arrow, similar to change input button for Kickstarter Dragon Forum Badge) steam-key was generated and now it says Delivered and "This Steam key cannot be destroyed.". I am not using Steam at all and really don't want it. As I said I never ask for steam-key, wasn't use it and not gave it to anyone else.

How to solve this problem?
