Thanks very much for giving me some more feedback. I'm trying to reproduce the problem in order to fix it. IDK, maybe it has to do with the incognito mode. For the time being, the downloadable version should work fine. :)
I think I know what causes the issue now. It seems to be related to the browser. You can try now, see if it works.:)
I see the title screen now! (which I didn't before)
