New at this server stuff..need help plzzzzzz

[zaenyea]

Ive wanted to create a Big Dig server since I couldnt find any to play on that I liked so I figured I would give it a shot. I installed everything to my server that came with the Big Dig server zip. I am able to launch and log into the world just fine. The problem comes when I try to get anything related to metallurgy precious metals or metallurgy ender metals. It says " No such item found with ID (insert number here whatever the item happens to be)". I tried it in single player and it works great...no problems with ender or precious metal items or the ore itself. Its not even generating those ores in the world that I could find. Any idea what my problem might be? Secondly, I installed thaumcraft. Its listed as installed under the mods and available BUT none of it even shows up on the server as if it wasnt there. Any help would be greatly appreciated. Thanks :)

did you install any mods on the server? sounds like you have mods client side that are not currently on the server
