No, when I open files -> choose "open with" -> then, click on ubotstudio .exe nothing happens. And when firstly launch Ubotstudio, then click on File > Open > Then browse for the .ubot file, Ubot says "Impossible to load bot because it is not a valid ubot file". I you have UbotStudio 5.9, please try by yourself with the files I attached in my first post. Thanks for your replies
