Resigning maps

Ok I got the new maps off my xbox and modded them. I applied the PPF patches and everything but when I go to play them on xbox live i get the You have failed to load the map. I didn't resign them. Do I need to resign them and if I do how do i do that?

 

yes u do need to resign them try usin cmr for the new maps and if u modded them with dot halo click fix encryption

 

use dothalo it works with all halo maps new and old

 

I already figured it out but thanks anyway.
