First, replace the file you edited with an unedited copy. That should get you back to normal.

It's most likely you made a mistake in editing some define in that file, or you edited it with something oher than a text editor. If you post the exact changes you were trying to make, we might spot something. Most commonly, Zenners try to ut text containing special characters (like apostrophes) in defines, and you can't do that without 'escaping' the character with a backslash:

'Alfonso\'s Place'

Also, please don't post the same question in multiple forums.
