Thank you very much for your answer! I don't know either, it never happened with any Renpy game before - as you said when there was something wrong then I got that ignore/rollback page but this one just freeze on that certain point (the first thing was that I searched for a comment with the same problem but it really seems like it's just me). I tried to go back to a previous choice and go with that but the result is the same. Then I'll reinstall it and remove the files from the AppData/Roaming etc folder too. It's not a problem that I'll loose my saves, I bet that I'll enjoy it for the second time to :) Thank you very much for your help and I'll write back that how it turned out!
