No Brushes Error
 

Not sure if anyone will spot this, but I'm running out of ideas on how to fix a problem. Everytime I try to create a map for JA I keep getting this error when I try to save or compile with GTKRadiant 1.4.0.

"ERROR: couldn't open C:/Program Files/LucasArts/Star Wars Jedi Knight Jedi Academy/GameData/base/maps/testNo brushes selected."

I scanned these forums and the internet with no luck for an answer. Any ideas on what could be causing this?
