Stuck after beating the Boss in the Tutorial

[Dark-Master.Barbzilla]

As per the Title, I am stuck after beating Zrull (or whatever his name is). After I kill him, it says something about how he is more powerful than ever, but there is nothing to click on to continue the text. I can't even press escape to view the menu. Third try and still sticking at this point, any suggestions (I've already tried reinstalling).
