Hey! So, I bought a minecraft server from a server hosting group, and they installed tekkit on it for me. It runs tekkit classic 3.1.2. And I have downloaded tekkit from your site today and for some reason its saying im missing some mods like mod_computercraft 1.41, mod_ccturtle 1.41, mod_ic2 v1.103 and mod_railcraft 5.4.7 . Does any one have any suggestions on how to fix this problem or where to get the mods if need be?
