My Mine is Dark...

I lit a torch, nothing, my friend lit 6 fires, still nothing.

like, pitch black? is there light around the ladder? i had a similar problem way back in the day, it was a video driver issue, make sure yours is up-to-date (from the manufacturer).

Yes, pitch black. I login and for half-a-second it was light, then it was dark again.
