Cannot go after intro movie

[DefinitelyCodex]

Hi everyone! Everytime I try to play this game, after the intro movie I get into the "Press a Key to continue" screen, but it doesn't do anything! I pressed every key of my keybord, it just stay here doing nothing (I'm starting to hate the music with all the time I listened it btw ahahah) I even tried to re-install it but it doesn't change anything. Can someone help me?
