Hi I got this problem started lately, and also I just wanted to get it fixed cause I made it with a lot of hard work and my device is Lenovo Tab 2 A7 30-GC , Also my other worlds can be opened except for this one
Kathryn you should have posted this in the support forum. You don't say what operating system you're using, but if it's Windows 7 you can try navigating to the minecraft saves folder and find your world that won't open and try right clicking the world folder and select 'restore previous version' from the drop down menu. Hopefully there are some older versions there you can roll back to from before your world got corrupted.
There is also a guide on the wiki that can help you recover some of your world if that doesn't work. You can find it here:
Before following those steps you should try renaming the file "level.dat_old" to "level.dat", replacing the original, and see if that fixes things; level.dat_old is a backup made every time level.dat is changed and consequentially may not be corrupted; you may lose a minute of progress (changes to your inventory or Ender chest) but you probably won't notice depending on what you were doing. Even worse, there is no mention of losing the world seed in that "tutorial", unless you manually entered or wrote down the seed.

Usually this happens to a world if minecraft crashes or a power outage happens while you're playing the world.

I tried it with terrible results. I gave my wife my glasses for a second, a creeper showed up and now my wife is pregnant.
Stupid 3D..

TheMasterCaver's First World - possibly the most caved-out world in Minecraft history - includes world download.
TheMasterCaver's World - my own version of Minecraft largely based on my views of how the game should have evolved since 1.6.4.
Why do I still play in 1.6.4?
