1. look what terrafirmacraft had to do
2. bash head against desk repeatedly
3. look at vanilla generation

you do realize terrafirma craft changes EVERYTHING, meaning that every single block what would naturally spawn in minecraft is replaced with a TFCraft block, leaving the old blocks in place... meaning you would have to start over anyway
try deleting the tekkit folder in your .techniclauncher folder, then download again. why? because i'm pretty sure something downloaded wrong, if the only thing it's loading is modloader
