Problem at ZDoomGL v0.5(the newest version)

I unzipped it to the directory where my doom was. And I had also unzipped the ZDoom v1.22 and the ZDoomGL's MD2 models. I can ran the game. But when I press any key, it also return to the desktop. Can anyone help me?

I can´t really help you - since I have similar Problems. I don´t get it - how can you start customs wads with Z-Doom? I have tried to install ZdoomGL v0.idon´tknow and it did not work, too.
