Minecraft world not working [duplicate]

I was playing in one of the snapshots for 1.9 in my survival world i think it was 15w49b and all the sudden my game crashed so i load back my launcher and the worlds not there but when i went to my saves folder its still there and im not sure why it wouldn't be showing i have a backup but it's from like 2 months before it crashed so it's not going to do me any good. Here is a picture of what the inside of my world folder looks like https://gyazo.com/8ee7892269f4d6c2c04a61020e6a631a please help!

The problem is that your level.dat file has disappeared, which contains information about the world (name, seed, generator options) and the player (inventory contents, location).

I created a new level.dat file that you should be able to paste into the world's folder to have it show up again:

Your world still contained level.dat_mcr, which is the level.dat from worlds before the Anvil format. This meant I could copy over the world's seed, which should hopefully prevent terrain generation issues.

I've put the data from your player's file that was in the playerdata folder (normally only read from in multiplayer/LAN, but written to in singleplayer) into level.dat, so you should keep your inventory as well.

I did this in 1.9pre2, so I'm not sure if you'll need to upgrade. (It's probably best not to be playing on outdated snapshots with known major bugs without frequent backups anyway)
