Help!

[Halo2Freak90]

Whenever I download or make a map using a ppf from here or one made by dot halo it always says failed to load the map, do you have any suggestions to help, ive tried to make vehicles come out of weopons on gemini, the gate on relic and the the flyable hog on triplicate, they all say failed to load the map, can anyone help?

perhaps u rnt signing the maps? otherwise, it could be balancing issues. make sure triplicate, and the other maps are in your maps folder in ur halo 2 folder in ur hdd.
