My problem is that while I was playing minecraft normally my computer crashed and now my saved world doesn't apper on my world list. If you can help me with this problem I would appreciated very much. :biggrin.gif:
This was my problem but I fixed it by deleting the level.dat and then renaming the level.dat_old to level.dat This is what I did to solve my problem if any of you have the same problem try what I did.
Remeber to make a back-up before you do this. Just in case it doesn't work :wink.gif:
