Can't enable the script anymore...

[Cullhwch]

Hey, I just recently edited the script (only to give the Celtic defenders Brihentin instead of Solduros) but now I can't enable the advisor any more. The "show me how" button is simply not selectable. Any ideas on how I can fix this short of reinstalling that file?

::Edit::

Nevermind, I found out that one instance of "unitceltic cavalry brihentin" was enough to kill the script. Mods, you can delete this if you want or leave it up as a warning to others.
