game Loads, Freezes then boots me out (disconnects)

Put the summary of the bug you're having here
This is one of my first (& more advanced regarding resources and achievements etc) it had crashed a while ago but I was able to Restore it using that "Mineback software" (my antivirus has since quarantined and removed Mineback due to security risks ie:Trojans). I continued to play this world, although I did Edit it's name to hint it may be glitched. But now it only loads for a second or so, then crashes every time.
What I expected to happen was...:
Describe what you thought should happen here

Describe what happened here
When I respawn in this world I'm unable to do anything but turn the camera for a second or so, but if I try to move or even check my Inventory the game crashes again

1. load the World named: 3rd World, possibly glitched??
2. after respawn try to move or collect items on the ground
3. It just crashes
