Compiling problem

I faced a new problem today when i was gonna compile my map and try it. I've tried it before and made some changes and now I got an error.

My compiling window with the error is here: http://img299.imageshack.us/my.php?image=felvu5.jpg

The result of this problem is that my light entities doesnt work. The whole map is very bright.

Greatful for answers

thanks it worked.
