Failed to load map error

I used to play H2 on live with an original XBOX and now I bought a 360 so I modded my regular box and now whenever I try to mod any multiplayer map for split screen or XBOX Connect use, I fail to load the maps. My campaign mods work fine. I have resigned my maps and tried doing the same mods with Dot Halo and with Insolence. I heard that I need a special resigner. Any help would be greatly appreciated.

 

try fixing the encryption with dothalo. Map tools> fix encryption

 

im sorry to say the latest updates for halo 2

won't allow modded maps

have fun

 

I finally found the map resigner that I needed but thanks anyway. My modded maps work fine now. If anyone wants a copy of the program, just send me a message at "angelluva126@hotmail.com"
