[Tekkit items not spawning Naturally]

I am playing on a tekkit server with my friends and i can spawn in tekkit mod items like the dark matter hammer and tin and copper etc.etc.etc but they do not occur naturally. I have reinstalled multiple times because right before this started happening i couldnt even spawn them in now I can spawn them in but nothing besides vanilla minecraft items spawn naturally. Any help would be appreciated. This happens with everyone not only me on my server.
