Minecraft Forums

I restarted my computer, and when I opened up minecraft again, I wasn't able to access any worlds, it looked like they weren't there, same with all the servers I saved and my texture packs. But when I went to the .minecraft file and then to saves, they were all still there. What is wrong? Is there a way to fix this? I already tried going to Edit Profile -> and to Game Directory and pasting the same location as the .minecraft file, even though it was the same, but it isn't working?

A world won't show up if the level.dat file is damaged.

Try re-naming the worlds maybe? I know when you delete a world the save file will still be in .minecraft.
