Help with JDoom

[MalachiX]

I am using the registered version of Doom. I have installed JDoom but whenever I launch, it gets to the title screen then quites. I have tried it on two different macnines and had the same problem. How do I fix?

Look at the doomsday.out, it might hold some clues as to what is happening. Most likely video driver related.
