sky not showing

Hi, I have created a sky, i have made a .dml, with my 6 textures showing, test_0001 - 0006. I have added it to my .mis file

materialList = "~/data/skies/test.dml";, and also in the editor. All my textures are in jpeg.

Opon loading, it either freezes, or displays a error,
MaterialList out of range, it's there, it seems like it wont work.

Any ideas?

Thanks
David

edit:fixed, I was missing the env map 0007
