Map wont build

[CASH]

I have been making my map for a while but when i save it, use mbuilder build it, put the bsp in the maps/dm folder none of my changes are saved. It still looks like it did a few days ago. I deleted like 5 things compilied the map and everything is still there when i check the map out. It has worked before and i dont notice anything differnet happening in the ms dos prompt when it is building. Any idea whats wrong.

Your map is failing to compile, or it is being saved as a different name in a different folder. Watch for errors as it compiles. Have it put your bsp in maps and then move it to the dm folder by hand.
