make SURE you have a backup before doing this (you could save the map under a new name, then open the original)
Go to brush>clean brushes, and press backspace to delete any brushes that are selected. Even if you think it's worked, keep the backup. Oh, and it's helpful to test regularly to avoid this sort of thing.

oh i,ve fixed it now i didnt want to tripple post cuz i though it would count as spamming, i copyied all the main brushes onto a blank map. them i overwrit the file then recompile then haypresto it works thanks all :D

good for you, great to see you fixed it.
Now, we want a map! :p

(lethal amout of sarcasum being used) Well You'll just have to wait then mr i wanna see the map after the whole thing didnt work basically its far from finished what i was doing was a test compile :D
