How to reset Shortcuts?

[Redmen1905]

Hi, when I start the game it says that Awakened POe Trade is running in the background but no shortcut works now. It might be I set a shortcut which I don´t remember so how can I now access the settings page again so that I can reset everything or is there another way to do it? I am not able to access the settings via shift+space.
Thanks upfornt for your support.
