Please attach the complete output of the "Game Output (Your Minecraft name) " which can be found on the fourth tab of the launcher to this ticket.
If the launcher closes after game start, please edit your profile and select "Launcher visibility" then, "Keep the launcher open".

Would it help if i uploaded the world for you?

Here is the Game Output http://pastebin.com/X6KWLWRh this is my command block world for a map i was working on and i have spent a lot of time on it.

See MC-87353

Ummm... this is not the same as the other one because mine is in the 1.9 snapshot the other one is in 1.8.8.

It's the same for the outcome:
[13:38:25] [Client thread/ERROR]: Exception reading C:\Users\Scott\AppData\Roaming\.minecraft\saves\SM\level.dat
java.util.zip.ZipException: Not in GZIP format
Your save game is broken.
Nothing we can do here.
You may restore a recent backup.
