If u want, upload u map to an filehoster and we look if we can fix it.

It seems to be working at the moment after using mcedit

I've got this same error but I have no experience with MCedit and I was wondering if someone could help me?

U can try this:
http://www.minecraftforum.net/topic/2728016-maccant-placebreak-blocks-in-one-area-of-my-world/#entry31956734

Or u upload u world (as an compress file, like ZIP, RAR or ACE) to an filehoster and give us the link, we will try to fix it for u.
