Known Fix:

 

[Byte Templar]

Your world is probably corrupted, take backup and try opening it with MCEdit. Sometimes you can manage to fix corrupted worlds with MCEdit.

dang it!! thanks for the help though much appreciated!

Look if there is a level.dat file inside the world folder if there isn't create a new world with a different name and copy that level.dat file over to your old world. I would suggest to make a backup first. This may also help.

I have had this before. I created a new world with the same name and when it loaded I had my old world back again. Don't know how or why some sort of ftb magic. It's worth a try
