Beat Demon Can't Get Out of Darklands

I finally beat the demon who killed Milder, but now I can't get out of the Darklands. *I've killed every monster about 10 times, gone round in circles and kept trying the warp machine, but nothing seems to work. *Help please!

Tried the warp machine as in pushed the red button?

Yes, but the warp machine does not respond.

keep pressing enter near the machine or restart the game.
